Example 111

Example 111: Because cardiac deaths appear to increase after heavy snow falls, an experiment was designed to determine the cardiac demands of manually shoveling snow.  Ten subjects cleared tracts of snow, and their maximum heart rates were recorded.    Their average maximum heart rate was 175 with a standard deviation of 15.  Assuming maximum heart rates are normally distributed, find the 95% confidence interval estimate of the population mean for those people who shovel snow manually.
