A local ice cream shop kept track of the number of cans of cold soda it sold each day, and the temperature that day, for two months during the summer. The data are displayed in the scatterplot below:A local ice cream shop kept track of the number of

The one outlier corresponds to a day on which the refrigerator for the soda was broken. Which of the following is true?

(a) A reasonable value of the correlation coefficient r for these data is 1.2.

(b) If the temperature were measured in degrees Celsius (C = 5/9 * (F-32)), the value of r would change accordingly.

(c) If the outlier were removed, r would increase.

(d) If the outlier were removed, r would decrease.

(e) Both (b) and (c) are correct.
