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

question 81

Short Answer

SCENARIO 7-7
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 Scenario 7-7,10% of all the samples of size 4 will have a sample mean of at least how many hours below the population mean?
