Calculate the sample estimate of the standard error of the mean. Show all work. b. Construct a 98% confident interval for the true population mean number of hours of sleep per night.
Sleep deprivation tends to interfere with a person's ability to concentrate, learn, and remember things. Although the amount of sleep needed per night differs among people, the National Sleep Foundation's recommendation for teens is eight to ten hours of sleep per night. Suppose a study of sleep in 36 students randomly selected from Blue Lake College found that they were getting a mean of 6.8 hours of sleep per night, with a sample standard deviation of 1.2 hours per night.
a. Calculate the sample estimate of the standard error of the mean. Show all work.
b. Construct a 98% confident interval for the true population mean number of hours of sleep per night. Show all work.
