Answer:
The 95% confidence interval estimate for the true proportion of adults residents of this city who have cell phones is (0.81, 0.874).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval estimate for the true proportion of adults residents of this city who have cell phones is (0.81, 0.874).
Answer:
25.3
1_ draw a triangle
the shortest side is a which will be 8(bunnies)
diagonal will be c ( what you need to find )
the last side will be b.
so the equation is a2+b2=c2 ( 2=squared)
that means..... 8x8+24x24=c
8x8=64
24x24=576
then add
576+64=640
the find square root
√640=25.2982212813
simplify to 25.3
you know your answer is correct because c is always the biggest side
Because they don’t have the same variables
The size of the overall population is <u>not important</u> in determining the reliability of a poll.
<h3>What is the purpose of the overall population in a poll?</h3>
The overall population that a poll is based on does not have anything significant to do with the poll itself which means that it is not important in determining reliability.
This is because the poll uses a sample of the population and not the population itself.
