A concerned professor wants to find out the average number of hours his students sleep. He asks his 15 students to tell him how many hours a night they sleep, the results reveal an average of 6.333 hours per day and standard deviation of s= 2.320 hours per day. Consider the above results as a random sample of all the professor's classes, construct and interpret a 90% confidence interval for the average number of hours of sleep. (Assume all assumptions are satisfied.) Round to the nearest thousandth. 90% CI: ( Interpretation: )

A concerned professor wants to find out the average number of hours his
students sleep. He asks his 15 students to tell him how many hours a night
they sleep, the results reveal an average of 6.333 hours per day and standard
deviation of s = 2.320 hours per day.
Consider the above results as a random sample of all the professor's classes,
construct and interpret a 90% confidence interval for the average number of
hours of sleep. (Assume all assumptions are satisfied.) Round to the nearest
