Question

Accepted Answer

Choice B is correct. The mean of a set of data values is the sum of all the data values divided by the number of data values in the set. The sum of the data values shown is 2 + 9 + 14 + 23 + 32 , or 80 . Since there are 5 data values in the set, the mean of the data shown is 80 5 , or 16 . Choice A is incorrect. This is the median, not the mean, of the data shown. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect. This is the maximum, not the mean, of the data shown.
