Conduct the following test at the α=0.10level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume that the samples were obtained independently using simple random sampling.Test whether p1≠p2 Sample data are x1=28, n1=254, x2=38, and n2=301.
(a) Determine the null and alternative hypotheses. Choose the correct answer below.
A. H0: p1=p2 versus H1: p1>p2
C. H0: p1=0 versus H1: p1=0
(b) The test statistic z0
is _____?
(Round to two decimal places as needed.)
is _____?
(Round to two decimal places as needed.)
(c) The P-value is
_____?
(Round to three decimal places as needed.)Test the null hypothesis. Choose the correct conclusion below.
A. Reject the null hypothesis because there is sufficient evidence to conclude that p1≠p2.
