Due to the popularity of smart watches and activity trackers, walking for fitness purposes is becoming more and more common. A random sample of 23 Americans is selected and their walking distances on a certain day are recorded. The sample had a mean walking distance of 2.2 miles and a standard deviation of 1.3 miles. Find a 95% confidence interval for the mean distance walked by Americans per day. You may assume that the variable is normally distributed. You must write a sentence interpretation that is specific to this problem.
