Consider the hypothesis test below. Ho : P1 - P2 0 Ha : P1 - P2 > 0 The following results are for independent samples taken from the two populations. Sample 1 Sample 2 n1 = 100 n2 = 300 P1 = 0.25 P2 = 0.13 Use pooled estimator of p. a. What is the p-value (to 4 decimals)? Use Table 1 from Appendix B. b. With a = 0.05, what is your hypothesis testing conclusion? Conclude the difference between the proportions is greater than 0 &gt
