Suppose we are interested in the average online exposure time of students, a random variable that can be described by a probability distribution. We are interested in deciding whether or not the mean exposure time is now greater than 8 hours per day average pre-COVID. Which could be a statement for the alternative hypothesis? A. µ = 8 hours per day B. µ ≠ 8 hours per day C. µ > 8 hours per day D. µ < 8 hours per day
