NEED HELP WITH "E" and "G" THANK YOU!!

Let x be a random variable that represents the batting average of a professional baseball player. Let y be a random variable that represents the percentage of strikeouts of a professional baseball player. A random sample of n = 6 professional baseball players gave the following information. 0.322 0.367 0.272 0.340 0.248 0.269 X. 3.5 7.8 4.0 8.6 3.1 11.1 (a) Verify that Ex = 1.818, Ey = 38.1, Ex? = 0.561822, Ey? = 295.87, Exy = 10.865, andrx -0.883.
