Question The normal daily high temperatures (in degrees Fahrenheit) in January for 10 selected cities are as follows: 46 49 73 56 34 65 35 78 55 38 The normal monthly precipitation (in millimeter) for these same 10 cities is listed here. 98 76 56 92 92 56 87 30 71 91 Which set is more variable? A. Temperature and precipitation have the same variability. B. Can not be determined C. Temperature is less variable than precipitation. D. Temperature is more variable than precipitation.

Step 1
For the temperature data: Mean = (46 + 49 + 73 + 56 + 34 + 65 + 35 + 78 + 55 + 38) / 10 = 52.9 Standard deviation = sqrt(((-6.9)^2 + (-3.9)^2 + (20.1)^2 + (3.1)^2 + (-18.9)^2 + (12.1)^2 + (-17.9)^2 + (25.1)^2 + (2.1)^2 + (-14.9)^2) / 10) ≈ 16.1 For the Show more…

The average annual rainfall in City A is 25 inches, with a standard deviation of 4 inches. The average annual rainfall in City B is 65 inches, with a standard deviation of 6 inches. In a given year, City A received 41 inches, while City B received 89 inches. Assuming both rainfall distributions are approximately normal, which city had the wetter year relative to its average distribution? A. City A B. City B C. The cities had equally wet years. D. Cannot tell from the information given.
