Bagel nutrition (2.3, 2.4) The scatterplot shows the relationship between calories and total carbohydrates (in grams) for 19 varieties of bagels sold by a national chain of bagel stores.

1. The correlation for these data is r = 0.915. Interpret this value in context.
2. How would the correlation be affected if carbohydrates were measured in ounces instead of grams? (1 gram = 0.035 ounces.)
3. The three data points in the lower left represent three special low-calorie bagels. How would the correlation be affected if these three bagels were removed from the data set?
