II. A random sampie of 30 TOur-member families visiting Disneyworld was selected, and the average
amount spent by these families on their Disneyworld visit was $825.75. The population standard
deviation is $98.25. Find the 90% confidence interval for the true population mean. Express the
interval endpoints to the nearest cent.

13. Use Z-scores to determine which is a better relative golf score (remember that in golf, lower scores
are better): Shooting a 75 in Tournament A where the mean score is 73 and the standard deviation is
3.4; or shooting a 76 in Tournament B where the mean score is 74 and the standard deviation is 3.6 .
