Assume that the heights of woman in 12th grade in the Virginia is 61.5 inches and the standad deviation is 6.5 inches. If groups of size 9 are randomly chosen and the means plotted, what is the probability of selecting a group whose height is between 56 and 58 inches? Remember, area = probability. Even with rounding your answer should be very close to the correct choice.
1. .1228
2. .8970
