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. A survey of sleep hours was taken during a Statistics class. 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?

Are treatment assignments classified as categorical data or quantitative? Example Treatment 1 840 total people receiving  40 died, 20 died past week 4, 10 developed health issues  Treatment 2 850 people receiving  30 died, 15 died past week 4, 9 developed health issues  Control 600 people received Placebo 33 died, 32 died past week 4, 8 developed health issues  Would this just be numerical (qualitative data) or because they are categorized into treatments it would overall just be categorical data?
