Question

A set of 125 golf scores are normally distributed with a mean of 76 and a standard deviation of three

b) what is the probability that a score is no

more than 79?

c) about how many scores fell between one

standard deviation of the mean?

Answer 1

see below

Explanation:

79 is one standard dev above the mean

approx 84 % would be less

( which seems a bit weird when discussing golf scores)

Between 1 SD below and 1 SD above encompasses just about 68%

.68 * 125 = ~ 85 scores
