The times that college students spend studying per week have a distribution skewed to the right with a mean of 8.6 hours and a standard deviation of 2.8 hours. Find the probability that the mean time spent studying per week for a random sample of 49 college students would be between 8.2 and 8.9 hours. Round your answer to two decimal places.

For a 4-unit class like Statistics, students should spend average of 12 hours studying for the class. A survey was done on 23 students, and the distribution of total study hours per week is bell-shaped with a mean of 13 hours and a standard deviation of 3.4 hours. Use the Empirical Rule to answer the following questions. a) 68% of the students spend between hours and hours on Statistics each week. b) 95% of the students spend between hours and...
