Imagine you are doing an Independent-Samples t-test. For Sample 1, you get n=10, M=17.2, SS=120. For Sample 2, you get n=12, M=19.1, SS=110. What are the correct pooled variance, estimated standard error, and t-obtained?

Group of answer choices:

Pooled variance = 11.50, estimated standard error = 1.45, t-obtained = -1.31

Pooled variance = 11.50, estimated standard error = 3.45, t-obtained = +2.91

Pooled variance = 22.50, estimated standard error = 3.45, t-obtained = -1.31

Pooled variance = 11.50, estimated standard error = 1.45, t-obtained = +2.91
