Required

A set of 125 golf scores are normally distributed with a mean of 76 and a standard deviation of 3.
How many scores fell within one standard deviations of the mean?

BE CAREFUL WITH THIS ONE AND READ CAREFULLY!!

THIS IS ASKING FOR 'HOW MANY SCORES' SO MULTIPLY THE % (AS A DECIMAL) BY THE TOTAL NUMBER OF SCORES IN THE DISTRIBUTION.

Round your answer to the nearest whole number, if necessary. (no units required)
