TABLE 7-1 Times Spent Studying by Students in the Week Before Final

question 36

Short Answer

TABLE 7-1
Times spent studying by students in the week before final exams follow a normal distribution with standard deviation 8 hours. A random sample of 4 students was taken from a population of 50 in order to estimate the mean study time for the population of all students. Use the finite population correction.
-Referring to Table 7-1, what is the probability that the sample mean differs from the population mean by less than 2 hours?
