Question 5 A sample has a mean of M = 63 and a variance of s2 = 36. If sample size is n = 9, what is the estimated standard error for the sample mean (sM)? A. 6.00 B. 4.00 C. 1.50 D. 2.00 Solution SEM = s/sqrt(n) = sqrt(var)/sqrt(n) = 2.00 => D..

1. Question 5 A sample has a mean of M = 63 and a variance of s2 = 36. If sample size is n = 9,
what is the estimated standard error for the sample mean (sM)? A. 6.00 B. 4.00 C. 1.50 D.
2.00
Solution
SEM = s/sqrt(n) = sqrt(var)/sqrt(n) = 2.00 => D.
