Question

Conduct a test at the alphaαequals=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 p1>p2. The sample data are x1=128​, n1=246​, x2=134​,n2=312.

​(b) Determine the test statistic.

z0=

​(Round to two decimal places as​ needed.)

​(c) The​ P-value depends on the type of hypothesis test. The hypothesis test H0: p1=p2 versus H1: p1>p2 is a​ right-tailed test.

Since this is a​ right-tailed test, the​ P-value is P( z>z0).

Use the technology output to find the​ P-value, rounding to three decimal places.
