Using the Formula n=1/(ME)2 to Determine Sample
Size
When we want 95 % confidence and use the conservative estimate of p
= 0.5 , we can use the simple formula n = 1 M E 2 to roughly
determine the sample size needed for a given margin of error M E
. Use this formula to determine the sample size needed for a margin
of error of 0.04 .
Enter the exact answer.

Determine the sample size needed in forming a 95% confidence interval for a proportion with margin of error of 0.04. (Use the “safe approach” for the population proportion (i.e., p=.50) Repeat part a.) for a margin of error of 0.02.

Find the minimum sample size n necessary to estimate a population proportion p with a 95% confidence interval that has a margin of error m = 0.04. Assume that you don’t have any idea what p is so that you use the simpler formula for n (which comes from taking the more complicated formula for n and substituting p∗ = 0.5 into it).

In this exercise, we examine the effect of the confidence level on determining the sample size needed. Find the sample size needed to give a margin of error within plus or minus 4 with 99% confidence. With 95% confidence. With 90% confidence. Assume that we use σ=35 as our estimate of the standard deviation in each case. Round your answers up to the nearest integer. 99% n= 95%n= 90% n=

8. (9 pts) Suppose that we want to construct a 95% confidence interval to estimate the percentage of voters who would vote a candidate. We suggest that approximately 46% would vote for the candidate. Suppose that we want the margin of error for the confidence interval is no more than 1%. Determine how large the sample size should be.

Recall the formula for a proportion confidence interval is p^?zp^(1?p^)n?????????<p<p^+zp^(1?p^)n????????? Thus, the margin of error is E=zp^(1?p^)n????????? . NOTE: the margin of error can be recovered after constructing a confidence interval on the calculator using algebra (that is, subtracting p^ from the right endpoint.)
