A Bell Curve (Normal Distribution) has a mean of − 1 and a standard deviation of 1/8 . How many integer values O are within three standard deviations of the mean?	Pick:  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
