5000 students that attend local area high schools were asked how much time they spend on homework each month. Their answers were recorded in hours, and we’re told that their answers follow a Normal distribution. The results showed that the mean time spent on homework each month was 25 hours, with a standard deviation of 3 hours.
16. What percentage of these students spent between 25 and 29 hours each month on their homework?
17. What percentage of these students spent more than 29 hours on their homework ?
18. What percentage of these students spent between 20 and 26 hours each month on their homework?
- What percentage of these students spent less than 26 hours each month on their homework ?
