In order to determine an interval for the mean of a population with unknown standard deviation a sample of 61 items is selected. The mean of the sample is determined to be 23. The number of degrees of freedom for reading the t value is
a. 22
b. 23
c. 60
d. 61
Answer:
c. 60
Step-by-step explanation:
Given
[tex]n = 61[/tex] --- sample
[tex]\bar x = 23[/tex]
Required
Determine the degrees of freedom (df)
This is calculated as:

Find the correlation coefficient between x and y
X 57 58 59 59 60 61 62 64
Y 77 78 75 78 82 82 79 81
Answer:
0.603
Step-by-step explanation:
Given the data:
X 57 58 59 59 60 61 62 64
Y 77 78 75 78 82 82 79 81
The Correlation Coefficient, R value gives a measure of the degree of correlation between two variables, the dependent and independent variable. The correlation Coefficient value ranges from - 1 to 1. With negative values depicting a negative relationship and positive values meaning a positive relationship. The closer the R value is to + or - 1, the higher the strength of the relationship. With a value of 0 meaning 'no correlation'.
The correlation Coefficient value of the data above is 0.603, this gives a fairly strong positive correlation

Suppose that 5% of athletes at a certain university are using steroids or other
performance-enhancing drugs (PEDs). Unfortunately, the tests used to detect PEDs
aren't perfect. Suppose that 3% of athletes who are not using PEDs will test positive
and be accused of using PEDs. Meanwhile, 1% of athletes who are using PEDs will test
negative and escape detection. Calculate the probability that a randomly selected
athlete will test positive.
Answer:
There is a 8.11% of any randomly selected athlete to test positive.
Step-by-step explanation:
To make it easier, let's assume there are 100 athletes
5/100 have it
3/95 do not have it, but will test positive
1% of the 5 athletes who are using PEDs = 0.05%
This means that 4.95/100 will test positive
3/95 = 3.16%
(rounded, if you need a more precise answer, it's 3.1578947368421053)
3.16% + 4.95% = 8.11%

A bag contains white, blue and red ping-pong balls in the ratio 8 : 3 : 2. There are 10 balls. If 10 white and 10 blue balls are removed from the bag, the new ratio is ?
Answer:
the new ratio of white, red and blue balls is 6:2:1
Step-by-step explanation:
The computation of the new ratio is shown below:
If you have 10 red balls, so the blue balls is in proportion of 3:2 that means 15 would be the blue balls. In addition to this, the while balls is in proportion 8:2 = 4:1 so there is a 40 white balls
Now if 10 white and 10 blue balls would be eliminated
So there is 30 white, 10 red, 5 blue bals
Also
30 = 5 × 6
And,
10 = 5 × 2
so the new ratio of white, red and blue balls is 6:2:1
One customer purchases 8 bags of cat food and 2 bags of dog food. The total weight of the purchase is 44 pounds. Another customer purchases 5 bags of cat food and 2 bags of dog food. The total weight of the purchase is 35 pounds.

A rectangle is 29 feet long and 7 feet long. What is the area of this rectangle? 203 ft² 143 ft² 107 ft² 72 ft²
Answer:
203 ft²
Step-by-step explanation:
We need to use multiplication for the answer of this.
29 × 7 = 203
so that means that the answer in feet is 203 ft²

Answer:
The hikers are 5 miles apart.
Step-by-step explanation:
East + West = 3 miles apart (x-axis)
North + South = 4 miles apart (y-axis)
Then use the pythagorean theorem to find the distance between them.
sqrt(distance) = sqrt(3^2+4^2)
distance = sqrt(25)
distance = 5 miles
Find the volume of a cone with a base radius of 5 in. and a height of 12 in.
Answer:
V = 314
Step-by-step explanation:
Volume of a cone:
V = πr²(h/3)
Given:
r = 5
h = 12
Work:
V = πr²(h/3)
V = 3.14(5²)(12/3)
V = 3.14(25)(4)
V = 314
Answer:
The volume of the cone is 311.1in³.
Step-by-step explanation:
V = ⅓Bh where B = πr²
V = ⅓πr²h
V = ⅓(22/7)(5²)12
V = 0.33(3.142)(25)12
V = 311.1in³
For which equation is s = 6 not the solution?
4 s = 24
9 - s = 4
s + 6 = 12
s - 4 = 2
Answer:
9 - s = 4
Step-by-step explanation:
9 - 6 is 3, not 4, so thats the answer!
The equation is s = 6 not the solution is 9 - s = 4.
What is the equation?An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
For which equation is s = 6 not the solution?
1. The solution of the equation 4 s = 24 is;
[tex]\rm4 s = 24\\\\s=\dfrac{24}{4}\\\\s=6[/tex]
2. The solution of the equation 9 - s = 4 is;
[tex]\rm 9 - s = 4\\\\s=9-4\\\\s=5[/tex]
3. The solution of the equation s + 6 = 12 is;
[tex]\rm s + 6 = 12\\\\s=12-6\\\\s=6[/tex]
4. The solution of the equation s - 4 = 2 is;
[tex]\rm s - 4 = 2\\\\s=2+4\\\\s=6[/tex]
Hence, the equation is s = 6 not the solution is 9 - s = 4.

Answer:
There is nothing here to answer.
Step-by-step explanation:
What the question is asking you to do is
convert
[tex] \frac{20}{200} [/tex]
into a percentage.
First, we will divide the numerator and denominator by 2 to get the denominator to 100 , then from there, we can get the percentage value from the numerator.
[tex] \frac{20 \div 2}{200 \div 2} \\ = \frac{10}{100} [/tex]
From the fraction above, we can see that the 20 is 10% of 200 , from the numerator.
