Correct! The t test for independent means is used to compare means derived from unrelated samples. We have 2 independent groups here, children from Belize and children from Samoa. To compare these means we can use a t-test for independent means.
Before we do this test, we need to state a formal hypothesis. This hypothesis needs to be stated in terms of the Null, , and Alternative hypotheses, .
Recall that we had decided informally that our hypothesis (expectation) was as follows: Children in Samoa are further from their mothers than children in Belize. How would we state this in terms of our Null and Alternative hypotheses? (choose one of the hypotheses below by clicking on the picture)
