Three students scheduled interviews for summer employment at the Brookwood Institute. In each case the interview results in either an offer for a position or no offer. Experimental outcomes are defined in terms of the results of each student interview. (Let Y = the position is offered to a student and N = the position is not offered to a student.) (a) List the experimental outcomes. (Select all that apply.) (Y) (N) (Y, Y) (N, N) (Y, N) (N, Y) (Y, Y, Y) (Y, Y, N) (Y, N, Y) (N, Y, Y) (Y, N, N) (N, Y, N) (N, N, Y) (N, N, N) (b) Define a random variable that represents the number of offers made. x = the percentage of offers accepted x = the ratio of offers to rejections x = the number of rejections x = the number of experimental outcomes x = the number of offers Is the random variable discrete? Yes No
