The binomial random variable, x, may be used as the test statistic when testing hypotheses about the binomial parameter, p, when n is small (say, 15 or less). Use Table 2 in Appendix B and determine the p-value for each of the following situations.

a. H,.: p = 0.5. Ha: p 0.5, where n = 15 and x = 12 b. Ho:p = 0.8, Hap0.8, where n = 12 and x 4 c. Ho: p 0.3, Ha: p > 0.3, where n 14 and x 7 d. H:p 0.9, H p
