1. Solve the problem. What do you conclude about the claim below? Do not use formal procedures or exact calculations. Use only the rare event rule and make a subjective estimate to determine whether the event is likely. Claim: A die is fair and in 100 rolls there are 63 sixes.

2. Express the null hypothesis H0 and the alternative hypothesis H1 in symbolic form. Use the correct symbol (, p, ) for the indicated parameter.

A skeptical paranormal investigator claims that the proportion of Americans who have seen a UFO, p, is less than 2 in a thousand.

3. Assume that the data is normally distributed and the number of observations is greater than fifty. Find the critical z value used to test a null hypothesis.

= 0.05 for a two-tailed test.

4. Find the value of the z test statistic using z=npqp^p.

The claim is that the proportion of child drowning deaths attributable to beaches is more than 0.25, and the sample statistics include child drowning deaths with 30% of them attributable to beaches.

5. Use the given information to find the P-value.

The test statistic in a right-tailed test is z = 0.52.
