If a certain sample of data has a mean of 24.0 and a standard deviation of 3.0, which of the following values is more than 2.5 standard deviations from the mean?  Choose the correct choice from the following choices:  A) 12.0  B) 13.5  C) 17.0  D) 23.5  E) 16.5
The standard deviation is 3. 2.5 standard deviations, which is just 2.5 x 3.0 is 7.5. The only answer more than 7.5 away from the mean is 16.5.
