A sample of n = 8 scores has a mean of M = 10. After one score is removed from the sample, the mean for the remaining score is found to be M = 11. What was the score that was removed? A. x = 3 B. x = 8 C. It is impossible to determine with the information provided. D. x = 7 Solution x1 + x2.....x8 / 8 =10 x1+x2+...+x8 = 80 Now New Mean = 77 On subtracting we find Xremoved = 80-77 =3 A. is correct.
