Question
Conduct a test at the a = 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling.
Test whether p, > p. The sample data are x, = 122, n, = 251, x, = 140, and n, = 301.
(a) Choose the correct null and alternative hypotheses below.
O A. Ho: p, =p, versus H,: p, <p,
O B. Ho: P, = 0 versus H,: p, #0
O C. Ho: P, =p2 versus H,: p, #P2
O D. Ho: p, =p, versus H,: p, > P2
(b) Determine the test statistic.
Zn = (Round to two decimal places as needed.)
(c) Determine the P-value.
The P-value isO.
(Round to three decimal places as needed.)
What is the result of this hypothesis test?
O A. Do not reject the null hypothesis because there is not sufficient evidence to conclude that p, +p,-
O B. Reject the null hypothesis because there is sufficient evidence to conclude that p, <p,
OC. Do not reject the null hypothesis because there is not sufficient evidence to conclude that p, <p,.
O D. Do not reject the null hypothesis because there is not sufficient evidence to conclude that p, > p.
