very Tuesday from 10 am to 11 am an accounting class has virtual office hours. The partial pmf is shown on the ollowing table for the number of students attending office hours on Tuesdays based on past experience. Let X enote the number of students attended virtual office hours on a particular Tuesday. P(X = x) 0.06 1 0.11 2 k 3 0.29 4 k 5 0.23 9 0.04 ) How many students are expected to attend Tuesday office hours? ) What is the standard deviation of X? Suppose each student will take exactly 12 minutes to ask questions during Tuesday office hours. What are the mean and variance of the time (in minutes) spent answering questions during Tuesday office hours?
