Use Table 2 in Appendix B to determine the critical region used in testing each of the following hypotheses.
a. Ho: p = 0.5 and Ha: p > 0.5 where n = 15 and a = 0.05
b. Ho: p = 0.5 and Ha: p ≠ 0.3 where n = 14 and a = 0.05
c. Ho: p = 0.4 and Ha: p < 0.4, where n = 10 and a = 0.05
d. Ho: p = 0.7 and Ha: p_0.7 where n = 13 and a = 0.01
