Confidence interval estimate for mean number of hours

Ten randomly selected shut-ins were each asked to list how many hours of television they watched per week. The results were: 82 66 90 84 75 88 82 94 110 91

a. Find x-bar (calculator)

b. Find s (calculator)

c. How many degrees of freedom will you use in this problem?

d. Determine the 90% Confidence interval estimate for the mean number of hours of television watched per week by shut-ins.

Assume the number of hours is normally distributed.

e. what is the length of the 90% Confidence interval for µ?
