**MathGuru**, Thursday, June 23, 2011 at 6:41pmI'll give you a hint.

H1 tells you if the test is one-tailed or two-tailed. If H1 shows a specific direction, like > or <, then the test is one-tailed. If the test does not show a specific direction, then the test is two-tailed. Therefore, since H1 shows a specific direction, look at the appropriate table for a one-tailed test at .05 level of significance.

I'll let you take it from here.
