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 were obtained on a typical day. Researchers found that visually impaired students averaged 9.87 hours of sleep, with a standard deviation of 1.1 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...

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 8.778.77 hours of sleep, with a standard deviation of 2.062.06 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?
