For each hypothesis test, state the claim in mathematical notation, state H₀ and H₁, calculate the test statistic and p-value (unless given), state your decision about H₀ (reject or fail to reject), and state your conclusion in terms of the original claim.

1. At a 0.05 level of significance, test Bill Bradley’s claim that the majority of voters would vote for him. Assume that sample data consists of 1068 randomly selected voters, 540 of whom indicated that they would vote for Bradley.

2. The Sylvan Pharmaceutical Company makes tubes of antibacterial cream that are labeled as containing 4 ounces. In testing a claim that the mean content amount is less than 4 ounces, a p-value of 0.220 is obtained. What do you conclude? Explain.
