5. (12 pt, 3 each) The empirical cumulative distribution function (CDF) of a sample z=zi, . . . , zmis defined by The sum in the definition counts the number of data points that are less than or equal to t. Thus F(t) is the fraction of data points that are less then or equal to t. Suppose that r has four points: -3,-1, -1, and 5 a) Find the following values of the empirical CDF by using the formula...
