For each of the following, calculate the standard error of the difference scores (left(s_{bar{D}} ight)) and the

For each of the following, calculate the standard error of the difference scores \(\left(s_{\bar{D}}\right)\) and the \(t\)-test for dependent means.

a. \(N_{D}=25, \bar{X}_{D}=10.00, s_{\bar{D}}=8.00\)

b. \(N_{D}=5, \bar{X}_{D}=6.80, s_{\bar{D}}=4.71\)

c. \(N_{D}=16, \bar{X}_{D}=2.12, s_{\bar{D}}=2.17\)

d. \(N_{D}=20, \bar{X}_{D}=.80, s_{\bar{D}}=3.10\)
