Using diaries for many weeks, a study on the lifestyles of visually impaired students was conducted. The students kept track of many lifestyle variables including how many hours of sleep obtained on a typical day. Researchers found that visually impaired students averaged hours of sleep, with a standard deviation of hours. Assume that the number of hours of sleep for these visually impaired students is normally distributed.
Fourty percent of students get less than how many hours of sleep on a typical day?

A journal published a study of the lifestyles of visually impaired students. Using diaries, the students kept track of several variables, including number of hours of sleep obtained in a typical day. These vis impaired students had a mean of 9.3 hours and a standard deviation of 1.88 hours. Assume that the distribution of the number of hours of sleep for this group of students is approximately normal. Below what hours 85% of the visually impaired students have their sleep?...

Suppose we measure how much sleep students in first and second year at UVic get per night. A sample of 21 first year students slept an average of 7.9 hours per night with a standard deviation of 1.3 hours. A sample of 16 second year students slept an average of 6.8 hours per night with a standard deviation of 2.1 hours. Suppose we want to test if first year students sleep more than second year students. Assuming the number of...
