Question: 10. One sample has n = 4 scores with 55 - 100 and * second sample has a - 8 with SS - 140. a.

10. One sample has n = 4 scores with 55 - 100 and *

second sample has a - 8 with SS - 140.

a. Calculate the pooled variance for the Two simples.

h. Calculate the estimated standard error for the"

sample mean difference.

c. If the sample mean difference is 6 points. is this enough to reject the null hypothesis for a two-tailed test with a - 051

d. If the sample mean difference is 9 points, is thes enough to reject the null hypothesis for a two-tailed test with a = 032
