Transcribed Image Text:Conduct the following test at the a = 0.10 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c)
the P-value. Assume that the samples were obtained independently using simple random sampling.
Test whether p, # p2. Sample data are x, = 30, n, = 254, x, = 36, and n, = 302.
(a) Determine the null and alternative hypotheses. Choose the correct answer below.
O A. Ho: P1 =P2 versus H,: p, +P2
O B. Ho: P1 = P2 versus H,: p, > P2
O C. Ho: P1 = 0 versus H,: p1 = 0
O D. Ho: P1 = P2 versus H,: P1 <P2
(b) The test statistic zo is |. (Round to two decimal places as needed.)
(c) The P-value is
(Round to three decimal places as needed.)
Test the null hypothesis. Choose the correct conclusion below.
O A. Reject the null hypothesis because there is sufficient evidence to conclude that p, # p,.
O B. Do not reject the null hypothesis because there is not sufficient evidence to conclude that p, # p2.
O C. Do not reject the null hypothesis because there is sufficient evidence to conclude that p, > p,.
O D. Reject the null hypothesis because there is not sufficient evidence to conclude that p, <p2.
