Need to solve for 95% interval and 90% interval
You are given the sample mean and the population standard deviation. Use this information to construct the 90% and 95% confidence
intervals for the population mean. Interpret the results and compare the widths of the confidence intervals. If convenient, use technology
to construct the confidence intervals.
A random sample of 60 home theater systems has a mean price of $146.00. Assume the population standard deviation is $17.10.
Construct a 90% confidence interval for the population mean.
The 90% confidence interval is (142.37, 149.63 ).
(Round to two decimal places as needed.)
Construct a 95% confidence interval for the population mean.
