In which
z is the zscore that has a pvalue of .
The margin of error of the confidence interval is:
For this problem, we have that:
90% confidence level
So , z is the value of Z that has a pvalue of , so .
What sample size will produce a margin of error of 9% with 90% confidence level
This is n when M = 0.09. So
A sample size of 61 will produce a margin of error of 9% with 90% confidence level
