a. Compute a 90% confidence interval estimate for the population mean.
The 90% confidence interval for the population mean is from to
(Round to two decimal places as needed. Use ascending order.)
b. Show what the impact would be if the confidence level is increased to 95%. Discuss why this occurs. Select the correct choice below and fill in the answer boxes to complete your choice.
(Round to two decimal places as needed. Use ascending order.)
O A. The 95% confidence interval is from
which is wider than the interval in part a. This is because the margin of error is greater for a smaller confidence level.
B. The 95% confidence interval is from
which is narrower than the interval in part a. This is because the margin of error is greater for a smaller confidence level.
which is wider than the interval in part a. This is because the margin of error is greater for a higher confidence level.
C. The 95% confidence interval is from
D. The 95% confidence interval is from
which is narrower than the interval in part a. This is because the margin of error is greater for a higher confidence level.
