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 9.45 hours of sleep, with a standard deviation of 2.68 hours. Assume that the number of hours of sleep for these visually impaired students is normally distributed.
(a) What is the probability that a visually impaired student gets less than 6.8 hours of sleep?
answer:
(b) What is the probability that a visually impaired student gets between 6.3 and 8.93 hours of sleep?
answer:

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?...
