Question 187806
-------------------------
From National Weather Service records, the annual snowfall in the TopKick Mountains has a mean of 92 inches and a standard deviation  of 12 inches. If the snowfall from 36 randomly selected years are chosen, what is the probability that the snowfall would be less than 95 inches?
---------------------------------
t(95) = (95-92)/[12/sqrt(36)]= 1.5
-------------------------
P(x < 95) = P(t < 1.5 with df = 35) = 0.9287
