Suppose you are testing Ho: p = .29 versus Ha:p.29. A random sample of 740 items shows that 207 have this characteristic. With a.05 probability of committing a Type I error, test the hypothesis. For the p-value method, what is the probability of the observed z value for this problem? If you had used the critical value method, what would the two critical values be? How do the sample results compare with the critical values? Appendix A Statistical Tables (Round the value of z to 2 decimal places, e.g. 15.75. Round the value of p to 4 decimal places, e.g. 15.7595. Round the critical values and p to 3 decimal places, e.g. 15.754. Enter negative amounts using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).)
