Al Description: A study of the effects of smoking on sleep patterns is conducted. The measure observed is the time, in minutes, that it takes to fall asleep. These data are obtained: Smokers (A): 69.3 56.0 22.1 47.6 53.2 48.1 52.7 34.4 60.2 43.8 23.2 13.8 Nonsmokers (B): 28.6 25.1 26.4 34.9 29.8 28.4 38.5 30.2 30.6 31.8 41.6 21.1 36.0 37.9 13.9 (a) Find the sample mean and standard deviation (sd) for each group (20%). (b) Make a Histogram of the data sets A and B on the same line (20%). (c) Make a Dot plot of the data sets A and B on the same line (20%). (d) Make a Box plot of the data sets A and B on the same graph (20%). (d) Comment on what kind of impact smoking appears to have on the time required to fall asleep? Can you justify generalizing this to the respective populations? (20%)
