Assume you are given the following scores from two randomly drawn, independent samples:

X: 5, 7, 8, 9, 11 Y: 2, 4, 4, 7, 8

1. a)     State the hypotheses necessary to test whether the populations from which the samples were drawn differ from each other.

1. b)   Calculate sx and sy.

1. c)     Complete the test at the .05 level of significance and state your conclusions.
