If a certain sample of data has a mean of 20.0 and a standard deviation of 5.0, which of the following values is more than 2.5 standard deviations from the mean?	Pick.
A) 12.0 B) 13.5 C) 17.0 D) 23.5 E) 26.5
The standard deviation is 5. 2.5 standard deviations, which is just 2.5 x 5.0 is 12.5. The only answer more than 12.5 away from the mean is 13.5.
