Ho: µ1 - µ2 = 0

Ha: µ1 - µ2 not equal to 0

X1 = 237, X2 = 218

¬1 = 54, ¬2 = 63

n1 = 42, n2 = 35

a) Calculate the appropriate test statistic and interpret the result.

b) Calculate the p value and interpret the result.

**PsyDAG**, Saturday, November 30, 2013 at 4:26pmZ = (mean1 - mean2)/standard error (SE) of difference between means

SEdiff = √(SEmean1^2 + SEmean2^2)

SEm = SD/√n

If only one SD is provided, you can use just that to determine SEdiff.

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to the Z score.
