You may have heard someone say that drinking coffee will stunt your growth. To test this, college students were asked their heights and if they were coffee drinkers. The data file CoffeeHeight.txt has the results. Copy and paste this data set into the Descriptive Statistics applet.

a. Based on just how the distributions look, do you think there is an association between height and drinking coff ee? Is so, in what way? Explain.
b. Notice there are two peaks (or what is called bimodal) in the distribution of heights for the non–coffee drinkers? Why do you think the distribution has this feature?
c. Find the mean height for the coffee drinkers and the non–coffee drinkers. With this added information, do you think there is an association between drinking coffee and height? Explain.
d. Find the median height for the coffee drinkers and the non–coffee drinkers. With this added information, do you think there is an association between drinking coffee and height? Explain.
e. If you could find that coffee drinkers were significantly shorter than non–coffee drinkers in a study like this, would this show there is a tendency for coffee to stunt a person’s growth? Explain.
