The accompanying data are x = cost (cents per serving) and y = fiber content (grams per serving) for 18 high-fiber cereals rated by Consumer Reports
(www .consumerreports.org/health).

a. Compute and interpret the correlation coefficient for this data set.
b. The serving size differed for the different cereals, with serving sizes varying from 1„2 cup to 11„4 cups. Converting price and fiber content to €œper cup€ rather than €œper serving€ results in the accompanying data. Is the correlation coefficient for the per cup data greater than or less than the correlation coefficient for the per serving data?
