Question: Two separate samples receive two different treatments.
The first sample has n=9 with SS= 710, and the second has n =6 with SS = 460.
a. Complete the pooled variance for the two samples.
b. Calculate the estimated standard error for the sample mean difference.
c. If the sample mean difference is 10 points, is this enough to reject the null hypothesis using a two tailed test with a= .05?
d. If the sample mean difference is 13 points, is this enough to reject the null hypothesis using a two tailed test with a =.05?
