The term snowstorms of note applies to all snowfalls over 6 inches. The snowfall amounts forsnowstorms of note in Utica, New York, over a four-year period are as follows:7.1, 9.2, 8.0, 6.1, 14.4, 8.5, 6.1, 6.8, 7.7, 21.5, 6.7, 9.0, 8.4, 7.0, 11.5, 14.1, 9.5, 8.6What are the mean and population standard deviation for these data, to the nearest hundredth?

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

The term “snowstorms of note” applies to all snowfalls over 6 inches. The snowfall amounts forsnowstorms of note in Utica, New York, over a four-year period are as follows:7.1, 9.2, 8.0, 6.1, 14.4, 8.5, 6.1, 6.8, 7.7, 21.5, 6.7, 9.0, 8.4, 7.0, 11.5, 14.1, 9.5, 8.6What are the mean and population standard deviation for these data, to the nearest hundredth?

A	mean = 9.46; standard deviation = 3.74
B	mean = 9.46; standard deviation = 3.85
C	mean = 9.45; standard deviation = 3.74
