What is a 90% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving
The question is incomplete. Here is the complete question.
USA Today reported that 36% of adult drivers admit that they often or sometimes talk on a cell phone when driving. This was based on a random sample of 1004 adult drivers.
a) What is a 90% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving?
b) What is a 95% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving?
c) What is a 99% confidence interval for the true proportion of adult drivers who have often or sometimes talk on a cell phone when driving?
d) What do you notice?
Answer and Step-by-step explanation: The way to calculate confidence interval for proportions is by using the following formula:
[tex]z(\sqrt{\frac{p(1-p)}{n} } )[/tex]
where
p is the sample population proportion
n is the number of individuals in the sample
z is z-score associated of the % of confidence
a) A 90% confidence has a z-score of z = 1.645
Calculating:
Interval = [tex]1.645(\sqrt{\frac{0.36(1-0.36)}{1004} } )[/tex]
Interval = [tex]1.645(\sqrt{0.00023} )[/tex]
Interval = [tex]1.645(0.01515)[/tex]
Interval = 0.025
A 90% Confidence interval for true population is between 0.335 and 0.385.
b) A 95% confidence has a z-score of z = 1.96
Since the sample parameter didn't change, the interval will be:
Interval = 1.96(0.01515)
Interval = 0.03
For a 95% confidence, interval is between 0.33 and 0.39.
c) A 99% confidence has a z-score of z = 2.58
Interval = 2.58(0.01515)
Interval = 0.39
For a 99% confidence, interval is between -0.03 and 0.75
d) Confidence interval tells you how certain your results from polling or survey would represent the real population's behaviour. In the experiment above, as the percentage of certainty grows, closer the real population proportion actually is for adult drivers who often or sometimes talk on a cell phone when driving.

Answer:
-3/2
Step-by-step explanation:
The line crosses grid intersections at (-1, 2), (1, -1) and (3, -4). These points are separated by 2 units horizontally and 3 units vertically.
The rise (vertical change) is -3 for each run (horizontal change) of +2, so the ratio rise/run is -3/2. That is the slope of the line: -3/2.
What is the area of an rectangle with sides lengths of 5/12 foot and 2/3 foot
Answer:
The area of given rectangle is 5/18 square feet.
Step-by-step explanation:
Let l be the length of rectangle and w be the width of the rectangle.
Given information is:
Length = l = 5/12 foot
Width = w = 2/3 foot
The area of a rectangle is given by the formula
[tex]Area = Length*Width\\A = l*w[/tex]
Putting the values for width and length
[tex]A = \frac{5}{12} * \frac{2}{3}\\= \frac{10}{36}\\=\frac{5}{18}[/tex]
The area is 5/18 square feet.
Hence,
The area of given rectangle is 5/18 square feet.
I need help on listing the four points that have a distance of 8 from B, thank you!
Answers:
(12, 3)(-4, 3)(4, 11)(4, -5)A diagram is shown below.
===========================================================
Explanation:
First we locate point B at (4,3). The '4' in the x position means we've gone 4 units to the right of the origin, and the 3 in the y coordinate means we've gone 3 units up.
Now we need to find four points that are 8 units away from this central location. We'll ignore point A.
What we can do is add 8 to the x coordinate of point B to get x+8 = 4+8 = 12. Keeping the y coordinate the same, the point (12, 3) is exactly 8 units away from (4,3). Think of drawing a number line through those two points. Then we can note there are 8 spaces between (4,3) and (12,3). Or we can say "there are 8 spaces between 4 and 12" since that '3' doesn't really play much of a role in this case.
So (12,3) is one answer.
---------------------------------
Move back to point B(4,3)
Instead of adding 8 to the x coordinate, let's subtract 8 from it
x-8 = 4-8 = -4
Again the y coordinate is kept the same.
The point (-4, 3) is 8 units away from (4,3). The number line distance from -4 to 4 is 8 units.
So (-4,3) is another answer.
----------------------------------
Move back to point B
From this starting point, we can move 8 units up. Doing this means we add 8 to the y coordinate, while the x coordinate is kept intact.
(4,3) turns into (4,11) after doing so.
(4,11) is another answer.
---------------------------------
Move back to point B
From this point, we can move down 8 units to arrive at (4,-5). note how y-8 = 3-8 = -5. The x coordinate is kept the same.
(4,-5) is another answer.
----------------------------------
The four points we found were:
(12, 3)(-4, 3)(4, 11)(4, -5)which are four possible answers
Those points are found by going 8 units right, 8 units left, 8 units up and 8 units down in that order. Each time we started at point B as our center of operation. The use of the word "center" is done because we can form a circle of radius 8, and the center of the circle is at B(4,3). Any point on the circle's edge is exactly 8 units away from the center point B.
Refer to the diagram below. The four answers are the red points P,Q,R,S. The point T is another point that could be an answer, but it's not as easy to find compared to the four other points.

Answer:
answer can be either 5 square root 2 or 7.01
Step-by-step explanation:
you can cancel out 2 (outside of brackets) with 2( denominator of the fraction)
Answer:
[tex]5\sqrt{2}[/tex]
Step-by-step explanation:
The 2 in the denominator and outside the parenthesis both cancels out, which just leaves with the most simplified answer.
Which of the following geometric objects has a

The circumference of a circle is 6π ft. What is the area, in square feet? Express your answer in terms of
π
Please help
Answer:
Circumference of the circle 2π(radius)=6π ft
Therefore, radius=3 ft
Area=π(radius)²=π×3²=9π ft²
9π ft² is the right answer.
The area of circle is 9π square feet.
What is area?Area is the amount of area occupied by an object's flat (2-D) surface or shape.
The circumference of circle = 2πr
6 = 2πr
r = 3π
And the area of circle is πr².
The area of the circle = 9π
Therefore, the area of the circle is 9π square feet.
