1.

When 50 people used the 5-2 fast diet for one year, their mean weight loss was 5 pounds and the standard deviation was 4 pounds. Use a .05 significance level to test the claim that their average weight loss is greater than 2 pounds. Find the appropriate null and alternative hypotheses.

2.

For the problem above, find the value of the test statistic.

3.

For the problem above, find the P-value.

4.

For the problem above, find the critical value.

5.

Using either the P-value or the critical value, make a conclusion about this claim.
