Question 16

11!/ 3! = 39916800/ 24 = 6652800

Question 18

11P9 = 11! /(11-9)! = 11! /2! = 39916800/ 2 = 19958400

Question 19.

To evaluate correlation coefficient we require the values of x, y . xy , x2 and y2

r = [nxy - xy] / sqrt {[nx2 - (x)2] [ny2 - (y)2] }

r = [ 5 * 3155 - 187 * 82] / sqrt [(5 * 7344 - 1872) * (5 * 1368 - 822)]

r = 441/ sqrt [1751 * 116]

r = 441/ 450.68

r = 0.980
