Transcribed Image Text:Conduct the following test at the a= 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the critical value. Assume that the samples were obtained independer
sampling.
Test whether p, # p,. Sample data are x, = 30, n, = 255, x, = 38 and n, = 301.
(a) Determine the null and alternative hypotheses. Choose the correct answer below.
O Ho: p, = P2 versus H,: p, < p2
O Ho: P, = P2 versus H,: p, > p2
O Ho: P, = P2 versus H,: p, # P2
(b) The test statistic z, is . (Round to two decimal places as needed.)
(c) The critical values are +. (Round to three decimal places as needed.)
Test the null hypothesis. Choose the correct conclusion below.
O Reject the null hypothesis.
O Do not reject the null hypothesis.
