The sample data below have been collected based on a simple random sample from a normally distributed population. Complete parts a and b. 1 6 0 7 3 1 9 5 8 0 a) Compute a 95% confidence interval estimate for the population mean. The 95% 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 98%. Discuss why this occurs. The 98% confidence interval is from ____ to ____. (Round to two decimal places as needed. Use ascending order.) Compare this confidence interval to the one computed in part a to determine the impact of increasing the confidence level to 98%. Review the calculations for the confidence interval to determine the reason for this impact.

a) Compute a 95% confidence
The 95% 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 98%. Discuss why this occurs.
The 98% confidence interval is from ____ to ____. (Round to two decimal places as needed. Use ascending order.)
Compare this confidence interval to the one computed in part a to determine the impact of increasing the confidence level to 98%. Review the calculations for the confidence interval to determine the reason for this impact.
