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.
