2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

Question

Conduct a 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 the samples were obtained independently from a large population using simple random sampling.
Test whether p, > P2. The sample data are x, = 121, n, = 259, x, = 140, and n, = 313.
(a) Choose the correct null and alternative hypotheses below.
O A. Ho: P1 = P2 versus H,: P1 P2
O B. Ho: P1 = P2 versus H,: p1 > P2
O C. Ho: P1 = P2 versus H,:P1 <P2
O D. H: p, = 0 versus H,: p, #0
(b) Determine the test statistic.
Zn =(Round to two decimal places as needed.)
(c) Determine the P-value.
The P-value is
(Round to three decimal places
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, > p2.
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, + p2.
O D. Do not reject the null hypothesis because there is not sufficient evidence to conclude that p, <p,.
