Must us best XLSTAT printout for this question. A significance level of .05 is used for each hypothosis test and a confidence level of 95% is used for each confidence interval estimate.

A random sample of people who work 9-5 hours and a random sample of people who work shifts were asked how many hours of sleep they get per day on average. An appropriate F-test was performed and it was found that the null hypothosis of the F-test should be rejected. Can we infer that there is a difference in the number of hours people sleep depending on whether they work 9-5 or shifts?
