Activity 2.3 Complete the following table. Number Sample Mean x x - HE ( X - HE ) 2 (2,2) (2,4) (2,6) (2,8 (4, 4) Calculate the following: a. Mean of the sampling distribution of means. b. Variance of the sampling distribution of means. c. Standard Deviation of the sampling distribution of means.The formula to find the mean ly of the sampling distribution of means is: Hy = Ex n The formula to find the variance o', of the sampling distribution of means is: 02 + = E( X - HE) 2 n The formula to find the standard deviation of of the sampling distribution of means is: E(X- HE) 2 n
