Question:

A sample of difference scores from a repeatedmeasures experiment has a mean of MD 5 3 with a standard deviation of s 5 4.

a. If n 5 4, is this sample sufficient to reject the null hypothesis using a two-tailed test with a 5 .05?

b. Would you reject H0 if n 5 16? Again, assume a two-tailed test with a 5 .05.

c. Explain how the size of the sample influences the likelihood of finding a significant mean difference.
