Question 308673
The 99% confidence level means that you include 3 standard deviations from the mean.  In this case, the standard deviation is 7, and 3*7=21.  Now, from the mean of 97, both ADD and SUBTRACT 21:


97-21=76
97+21=118


The interval is from 76 to 118.  In other words, 99% of the golfers scored between 76 and 118 on this golf course.
