# Question: 1 The null hypothesis from a break even analysis should include

1. The null hypothesis from a break-even analysis should include the possibility that the methods are equally profitable.

2. A one-sided test of H0: m1 - Î¼2 â‰¤ 10 rejects H0 if 10 lies outside of the 95% confidence interval for Î¼1 - Î¼2.

3. If the standard two-sample t-test rejects H0: Î¼1 - Î¼2 . +100, then m1 is more than $100 larger than Î¼2.

4. If we double the size of both samples, we reduce the chance that we falsely reject the null hypothesis when using the two-sample t-test.

5. If the two-sample confidence interval for Î¼1 - Î¼2 includes 0, then we should conclude that Î¼1 = Î¼2.
