I need help with something regarding this problem. The National Sleep Foundation recommends that adults aged 18 to 64 get an average of 8 hours of sleep per night.

The data is listed below: 4, 5, 5, 5, 5.5, 6, 6, 6, 6, 7, 7, 7, 7, 7, 7, 7, 8, 8, 8, 8, 9, 9, 9, 10, 10 Do we have enough evidence at the 0.05 significance level to say that statistics students tend to get less sleep than the recommended average of 8 hours per night? How would I get the degrees of freedom?
