The scatterplot shown below displays the 2013 Minnesota State Fair daily attendance (Y) and the daily high temperature (X) for each of the 12 days of the fair.

a. For these data, r² equals .38. Calculate r. (Pay careful attention to the nature of the relationship between temperature and attendance.)

b. According to Cohen€™s guidelines, is the relationship between the high daily temperature weak, moderate, or strong?

c. Two data points in the scatterplot that are associated with the two lowest temperatures appear to be associated with fairly large prediction error. The coordinates of the two data points are (75, 236197) and (68, 164277). What might be a possible explanation for the relatively large prediction errors?
