the average score of all golfers for a particular course has a mean of 80 and a standard deviation of 5. suppose 100 golfers played the course today. find the probability that the average score of the 100 golfers exceeds 81
---
t(81) = (81-80)/[5/sqrt(100)] = 1/(1/2)= 2
------------
P(x > 81) = P(t > 2 when df = 99) = 0.0241
