How many rounds of golf do those physicians who play golf play per year? A survey of 12 physicians revealed the following numbers:
5, 42, 17, 4, 33, 41, 18, 14, 16, 32, 13, 50
Estimate with 99% confidence the mean number of rounds played per year by physicians, assuming that the population is normally distributed with a standard deviation of 6.
Note: For each confidence interval, enter your answer in the form (LCL, UCL). You must include the parentheses and the comma between the confidence limits.
