c. An earlier Z-test for the difference between two proportions in part (a) and (b) using the hypotheses Upper H 0: pi 1greater than or equalspi 2 and Upper H 1: pi 1less thanpi 2 resulted in a test statistic of Upper Z Subscript STATequalsnegative 9.05, with a p-value of 0.000. Compare the results of (a) and (b) to the results of the Z-test. Choose the correct answer below. A. The chi-square test concluded that the null hypothesis should be rejected, while the Z-test concluded that the null hypothesis should not be rejected. B. The chi-square test concluded that the null hypothesis should not be rejected, while the Z-test concluded that the null hypothesis should be rejected. C. Both tests agree that the null hypothesis should be rejected. D. Both tests agree that the null hypothesis should not be rejected. E. The tests cannot be compared since the Z-test was a one-tail test, while the chi-square test was a two-tail test
