A Bell Curve (Normal Distribution) has a mean of − 1 and a standard deviation of 1/8 . How many integer values M are within three standard deviations of the mean?  Options
A) 0	B) 1	C) 3	D) 6	E) 7
Got the question correctly -- the second item -- [highlight]bthe list of elements in the set is required.[/highlight] is not required.   With the new information, there is only one integer value (-1) that is between (-1.375, -0.625) i.e., falls within the three 3 SD range.1
