A Bell Curve (Normal Distribution) has a mean of − 1 and a standard deviation of 1/8 . How many integer values are within three standard deviations of the mean?	Choose the correct choice from the following options: A) 0 B) 1 C) 3 D) 6 E) 7
Mean = -1   Standard Deviation = 1/8   1 unit of standard deviation BELOW the mean = -1 - 1/8 = -1 1/8   2 units of standard deviation BELOW the mean = -1 - 1/8 - 1/8 = -1 2/8   2 units of standard deviation BELOW the mean = -1 - 1/8 - 1/8 - 1/8 = -1 3/8   1 unit of standard deviation ABOVE the mean = -1 + 1/8 = -7/8   2 units of standard deviation ABOVE the mean = -1 + 1/8 + 1/8= -6/8   3 units of standard deviation ABOVE the mean = -1 + 1/8 + 1/8 + 1/8= -5/8   So, all values from -1 3/8 to -5/8 are within 3 standard deviations of the mean.   Within this range, there is only 1 integer value: -1   Answer:3
