Step-by-step explanation:
A biologist studying trees constructed the confidence interval (0.14, 0.20) to estimate the proportion of trees in a large forest that are dead but still standing. Using the same confidence level, the interval was later revised because the sample proportion had been miscalculated. The correct sample proportion was 0.27. Which of the following statements about the revised interval based on the correct sample proportion is true?
A) The revised interval is narrower than the original interval because the correct sample proportion is farther from 0.5 than the calculated proportion is
B) The revised interval is narrower than the original interval because the correct sample proportion is closer to 0.5 than the mis-calculated proportion is
C) The revised interval is wider than the original interval because the correct sample proportion is farther from 0.5 than the mis-calculated proportion is
D) The revised interval is wider than the original interval because the corect sample proportion is closer to 0.5 than the mis-calculated proportion is.
E) The revised interval has the same width as the original interval.
Answer:
D) The revised interval is wider than the original interval because the corect sample proportion is closer to 0.5 than the mis-calculated proportion is.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
The larger the closer to 0.5 the value of [tex]\pi[/tex], the larger the margin of error and the wider the interval is.
A biologist studying trees constructed the confidence interval (0.14, 0.20)
This means that the estimate used was of:
[tex]\pi = \frac{0.14 + 0.2}{2} = \frac{0.34}{2} = 0.17[/tex]
The correct sample proportion was 0.27.
With [tex]\pi = 0.27[/tex], the margin of error is larger as 0.27 is closer to 0.5 than 0.17. Thus, the revised interval will be wider, and the correct answer is given by option D.
10. What value of x and y will make the polygon a
parallelogram?
Answer:
Step-by-step explanation:
20 = 5y
4=y
x+3y = 2(x+y-1)
x+3y = 2x +2y -2
x+3(4) = 2x + 2(4) -2
x +12 = 2x +8 -2
12-8+2 = 2x -x
6 =x
The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal, and opposite angles equal.
Given is a polygon,
We know opposite sides of a parallelogram are equal,
Therefore,
5y = 20
y = 20/5
y = 4
And,
Putting y = 4, in x+3y = 2(x+y-1)
x+12 = 2(x+3)
x+12 = 2x+6
x = 12-6
x = 6
Hence, The values of x and y that makes the polygon a parallelogram is 6 and 4 respectively.

.11 A machine produces metal pieces that are cylindrical in shape. A sample of pieces is taken, and the diameters are found to be 1.01, 0.97, 1.03, 1.04, 0.99, 0.98, 0.99, 1.01, and 1.03 centimeters. Find a 99% confidence interval for the mean diameter of pieces from this machine, assuming an approximately normal distribution.
Answer:
The 99% confidence interval for the mean diameter of pieces from this machine is between 0.93 and 1.07.
Step-by-step explanation:
Sample mean:
Sum of all values divided by the number of values. So
[tex]M = \frac{1.01+0.97+1.03+1.04+0.99+0.98+0.99+1.01+1.03}{9} = 1[/tex]
Sample standard deviation:
Square root of the sum of the differences between each value and the mean, divided by the 1 less than the sample size. So
[tex]s = \sqrt{\frac{(1.01-1)^2+(0.97-1)^2+(1.03-1)^2+(1.04-1)^2+(0.99-1)^2+(0.98-1)^2+(0.99-1)^2+(1.01-1)^2+(1.03-1)^2}{8}} = 0.0657[/tex]
Confidence interval:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 9 - 1 = 8
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 8 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.99}{2} = 0.995[/tex]. So we have T = 3.355
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 3.355\frac{0.0657}{\sqrt{9}} = 0.07[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 1 - 0.07 = 0.93
The upper end of the interval is the sample mean added to M. So it is 1 + 0.07 = 1.07
The 99% confidence interval for the mean diameter of pieces from this machine is between 0.93 and 1.07.
please explain why. In a competition of 50 professional ballroom dancers, 22 compete in the fox-trot competition, 18 compete in the tango competition, and 6 compete in both the fox-trot and tango competitions. How many dancers compete in the fox-trot or tango competitions?
Answer: 34 of them do
Step-by-step explanation: It says that 22 of them compete in the fox-trot and then it says 18 compete in the tango and then at the end it says that 6 compete in both. Based on what that said I can confirm that it's 36 because the question they want us to answer is only the ones who do fox-trot or tango not both
Hope this helps :)
Answer:
22+18-6=34
Step-by-step explanation:
Let's call F the set of dancers who dance fox-trot (not necessarily just that, they may also dance something else, what's important is that, amongst other things, they also dance fox-trot), and T the set of dancers who dance tango.
We know that F has 22 elements, T has 18, and the intersection of sets F and T (e. g. those who dance both tango and fox trot) has 6 ones.
Now, let's take a further look at how those sets are made up.
Let's take set F, for example. In it, there is some number of dancers who dance only fox trot, and some others who dance both fox trot and tango.
Similarly, set T is made up of those who dance only tango and those who dance both fix trot and tango.
Therefore, if we were to add those sets together, we would get the number of those who only dance tango, plus the number of those who only dance fox trot, plus two times the number of those who dance both.
We can make up for that, and get the desired result, by subtracting the union of sets F and T from their sum.
Hope this was a clear explanation :)

find the probability of at least 6 failures in 7 trials of a binomial experiment in which the probability of success in any trial is 9%
Answer:
0.8746 = 87.46% probability of at least 6 failures in 7 trials.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
7 trials
This means that [tex]n = 7[/tex]
The probability of success in any trial is 9%?
So the probability of a failure is 100 - 9 = 91%, which means that [tex]p = 0.91[/tex]
Probability of at least 6 failures in 7 trials?
This is:
[tex]P(X \geq 6) = P(X = 6) + P(X = 7)[/tex]
In which
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 6) = C_{7,6}.(0.91)^{6}.(0.09)^{1} = 0.3578[/tex]
[tex]P(X = 7) = C_{7,7}.(0.91)^{7}.(0.09)^{0} = 0.5168[/tex]
[tex]P(X \geq 6) = P(X = 6) + P(X = 7) = 0.3578 + 0.5168 = 0.8746[/tex]
0.8746 = 87.46% probability of at least 6 failures in 7 trials.

Let the angles be ABC (See attachment 2)
[tex]\angle CAB[/tex] is corresponding to 50 degrees. So:
[tex]\angle CAB=50[/tex]
[tex]\angle ABC[/tex] is corresponding to 55 degrees. So:
[tex]\angle ABC = 55[/tex]
This means that:
[tex]\angle ABC + \angle CAB + x = 180[/tex]
[tex]50 +55 + x = 180[/tex]
Solve for x
[tex]x = 180 - 50 - 55[/tex]

The r-value of the given data is 0.374.
What is a correlation coefficient?The correlation coefficient, denoted as r, is a statistical measure that describes the strength and direction of the linear relationship between two variables.
It ranges between -1 and +1, where -1 indicates a perfect negative correlation (inverse relationship), +1 indicates a perfect positive correlation (direct relationship), and 0 indicates no correlation between the variables.
We have,
First, we need to find the correlation coefficient (r) of the given data.
We can use the following formula to do this:
r = [n∑(xy) - (∑x)(∑y)] / [√{n∑x² - (∑x)²} √{n∑y² - (∑y)²}]
where n is the number of data points, x, and y are the respective variables, and ∑ denotes the sum of the values.
Using the given data, we can calculate the values as follows:
n = 5
∑x = 39
∑y = 53
∑(xy) = 442
∑x^2 = 483
∑y^2 = 1249
Substituting these values into the formula, we get:
r = [5(442) - (39)(53)] / [√{5(483) - (39)^2} √{5(1249) - (53)²}]
r = [2210 - 2067] / [√(2415) √(5660)]
r = 143 / (61.898 75.245)
r = 0.374 (rounded to three decimal places)
Therefore,
The r-value of the given data is 0.374.

what is the measure of angle KIT?
Answer:
80°
Step-by-step explanation:
In rhombus, opposite angles are equal. i.e <KET = <KIT
Triangle KET is isoceles, which means both parts of angle E are equal.
Angle E = 40 + 40
Angle E = 80
If angle E is 80 than Angle I is also 80.
If m∠P = (19x - 5)° and x = 4, find m∠P and classify the angle (acute, right, obtuse, straight).
Answer:
71 degrees, Acute angle
Step-by-step explanation:
From the question, the equation for the Angle is given to be 19x-5, given in degrees and they want to find the value of the angle when the variable X is equal to 4.
All we need to do is change X with 4 in this equation to get
(19x4)-5) Now we just need to do some basic arithmetic to find out the value.
(76-5)=71, So 71 degrees. Now let's classify all the types of angles
1-89 degrees is a acute angle
90 degrees Is a right angle
91-179 is a obtuse angle
180 is a Straight angle
181-359 is a reflex angle
360 is a full turn.
Notice how our 71 degree angle falls into the category of a acute angle (1-89)
So our final Answer is that the angle is 71 degrees and a acute angle.
Answer:
∠ P = 71° and is acute
Step-by-step explanation:
Acute angle is between 0° and 90°
Right angle = 90°
Obtuse angle is between 90° and 180°
Straight angle = 180°
Given
∠ P = 19x - 5 ← substitute x = 4
= 19(4) - 5 = 76 - 5 = 71° ← acute angle
