If a certain sample of data has a mean of 20.0 and a standard deviation of 2.5, which of the following values is more than 2.5 standard deviations from the mean?
Choose the correct choice from the following:	A) 22.0	B) 13.5	C) 17.0	D) 23.5	E) 12.0
The standard deviation is 2.5. 2.5 standard deviations, which is just 2.5 x 2.5 is 6.25. The only answer more than 6.25 away from the mean is 12.0.
