Assuming that the difference between two independent sample means is 6.24, and S2difference = 27, what is the calculated t score?

A) (6.24 + 2) / 27 = 0.31
B) (6.24 + 2) / 27 = 8.24 / 5.20 = 1.58
C) 6.24 / 27 = 0.23
D) 6.24 / 27 = 6.24 / 5.20 = 1.20

Question 2

ased on the following results, which would be the correct use of the formula, t = (M1 M2) / Sdifference? Sample 1: Mean = 60; Variance of the distribution of means = 2 Sample 2: Mean = 50; Variance of the distribution of means = 7

A) t = (7 2) / (50+60)
B) t = (60 50) / (22+72)/2
C) t = (60 50) / (2+7)
D) t = (60 50) / (2+7)
