Consider the hypothesis test below. Ho : P1 - P2 SO Ha: P1-P2 > 0 The following results are for independent samples taken from the two populations. Sample 1 Sample 2 n1 = 200 n2 = 300 P1 = 0.28 P2 = 0.19 %3D %3D Use pooled estimator of p. a. What is the value of the test statistic (to 2 decimals)? 2.64 b. What is the p-value (to 4 decimals)? 0.0041 c. With a = .05 , what is your hypothesis testing conclusion? Conclude the difference between the proportions is greater than 0
