Calculate the mean of the data set below. (Round to the nearest hundredth. 10.3, 1.5, 3.8, 2.6, 1.5, 9.1, 4.2, 3.8, 1.5, 2.9

A. 3.12 B. 3.30 C. 3.52 D. 3.81

The answer is 4.12

I don't know why this answer isn't any of the choices, but you calculate the mean by adding up the values and then dividing by the number of values. In this case, the total is 41.2, and there were ten values to add up to get that number, coming out to be 4.12
