If a certain sample of data has a mean of 20.0 and a standard deviation of 2.0, which of the following values is more than 2.5 standard deviations from the mean?	Pick one:	A) 13.5	B) 12.0	C) 17.0	D) 23.5	E) 26.5
The standard deviation is 2.0. 2.5 standard deviations, which is just 2.5 x 2.0 is 5.0. The only answer more than 6.0 away from the mean is 12.0.
