Answer
B. The mean for this population is $\mu$ = 5. The smallest distance from the mean is 1 point and the largest distance is 3 points. The standard distance should be between 1 to 3 points.
C. Mean = $\mu$ = $(8+6+5+2+6+3+5)/7$ =5
Variance = mean squared deviation = $24/6$ = 4
Standard deviation = $\sqrt s^2$=$\sqrt 4$ = 2
