The attendence records (abscences) of 20 students in a class were recorded due to sickness. Here are the results: 0, 3, 2; 2, 6,0, 1,0,0,1,0,2,0,1, 1, 0, 4, 0, 0,4 Find the mean number of days lost Find the variance of days lost Assume each observation occurs with a probability of 1/20 - P(X) = 1/N Use the example I used in class (page 25 of class notes) as a template for how to create the table below. M 2 0 Create a table to calculate the mean and variance using the following formulaes: E[x] = [X PRob (X) E[x]-M
