Question
Conduct a test at the α= 0.01 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 p1 > p2 . The sample data are x1 = 122, n1 = 241, x2 = 132, and n2 = 314.
- Choose the correct null and alternative hypotheses
- H0 : p1 = p2 versus H1 : p1 > p2
- H0 : p1 = 0 versus H1 : p1 ≠ 0
- H0 : p1 = p2 versus H1 : p1 ≠ p2
- H0 : p1 = p2 versus H1 : p1 < p2
- Determine the test
z0 = _______________ (Round to two decimal places as needed.)
- Determine the P-value.
The P-value is .
(Round to three decimal places as needed.) What is the result of this hypothesis test?
- Do not reject the null hypothesis because there is not sufficient evidence to conclude that p1 < p2 .
- Reject the null hypothesis because there is sufficient evidence to conclude that p1 < p2 .
- Do not reject the null hypothesis because there is not sufficient evidence to conclude that p1 > p2 .
- Do not reject the null hypothesis because there is not sufficient evidence to conclude that p1 ≠ p2 .
