17. The test statistic of $z = 1.00$ is obtained when testing the claim that $p > 0.3$. 18. The test statistic of $z = -2.50$ is obtained when testing the claim that $p < 0.75$. 19. The test statistic of $z = 2.01$ is obtained when testing the claim that $p \neq 0.345$. 20. The test statistic of $z = -1.94$ is obtained when testing the claim that $p = 3/8$. Critical Values. In Exercises 21-24, refer to the information in the given exercise and do the following. a. Find the critical value(s). b. Using a significance level of $\alpha = 0.05$, should we reject $H_0$ or should we fail to reject $H_0$? 21. Exercise 17 23. Exercise 19 22. Exercise 18 24. Exercise 20
