. The most recent American Time Use Survey, conducted by the Bureau of Labor Statistics, found that many Americans barely spend any time reading for fun. People ages 15 to 19 average only 7.8 minutes of leisurely reading per day with a standard deviation of 5.4 minutes. However, people ages 75 and over read for an average of 43.8 minutes per day with a standard deviation of 35.5 minutes. These results were based on random samples of 975 people ages 15 to 19 and 1050 people ages 75 and over. Construct and interpret a 95% confidence interval for the difference in mean amount of time (minutes) that people age 15 to 19 and people ages 75 and over read per day.
