A study explored the effect of ethanol on sleep time. Fifteen rats were randomized to one of three treatments. Treatment 1 was water (control). Treatment 2 was 1g of ethanol per kg of body weight, and Treatment 3 was 2g/kg. The amount of REM sleep (in minutes) in a 24hr period was recorded:
Treatment 1 | 63 | 54 | 69 | 50 | 72 | |
Treatment 2 | 45 | 60 | 40 | 56 | ||
Treatment 3 | 31 | 40 | 45 | 25 | 23 | 28 |
Are these data strong evidence REM sleep time differs across the three treatment populations?
Use R to create 95% CIs for all pairwise comparisons of means using the Tukey-Kramer method. Give the r code that gives the 95% CIs. Summarize your results using letter codes. What do you conclude?

I only need help with (e) and (f). Thanks! Please show work by hand 1. A study was conducted to explore the effects of ethanol on sleep time. Fifteen rats were randomized to one of three treatments. Treatment 1 got only water (control). Treatment 2 got lg of ethanol per kg of body weight, and treatment 3 got 2g/kg of ethanol. The amount of REM sleep in a 24hr period was recorded, in minutes. Data are below: Treatment 1: 63,...
