I need help with this solution.....

Randomly selected students participated in an experiment to test their ability to determine when one minute(or sixtyseconds) has passed. Forty students yielded a sample mean of 60.6 seconds. Assuming that =8.8 seconds, construct and interpret a 99% confidence interval estimate of the population mean of all students.

What is the 99% confidence interval for the population mean ?

_ < < _

(Type integers or decimals rounded to one decimal place asneeded.)

Based on theresult, is it likely that thestudents' estimates have a mean that is reasonably close to sixtyseconds?

A. Yes, because the confidence interval does not include sixty seconds.

B. No, because the confidence interval does not include sixty seconds.

C. Yes, because the confidence interval includes sixty seconds.

D. No, because the confidence interval includes sixty seconds.
