Question
The most recent American Time Use Survey 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. A 95% confidence interval constructed for the true difference in mean amount of time in minutes spent reading per day (15 to 19 - 75 and older) was −36±2.1762−36±2.1762. Does the interval provide convincing evidence that those 75 and older read more than those 15 to 19?
