A random sample of daily rainfall in millimeters (mm) for 14 June days in Oregon, had a mean rainfall of 23.88 mm and a standard deviation of 2.26 mm. A random sample of 12 high temperatures in Fahrenheit (F) for June days in Oregon, had a mean temperature of 76.1 and a standard deviation of 6.16. Which has a greater variation and why? a. The temperatures have the greater standard deviation, so therefore the greater variation. b. The temperatures have the greater mean, so therefore the greater variation. c. Rainfall has the greater coefficient of variation, so therefore the greater variation. d. The rainfall has more variation since there are more rainfall data points. The larger the sample the more variation there will be
