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=120,

n1=248,

x2=133,

and

n2=302.

(a) Choose the correct null and alternative hypotheses below.

Upper H 0 : p 1 equals p 2H0: p1=p2

versus Upper H 1 : p 1 not equals p 2H1: p1≠p2

Upper H 0 : p 1 equals p 2H0: p1=p2

versus Upper H 1 : p 1 less than p 2H1: p1<p2

Upper H 0 : p 1 equals 0H0: p1=0

versus Upper H 1 : p 1 not equals 0H1: p1≠0

Upper H 0 : p 1 equals p 2H0: p1=p2

versus Upper H 1 : p 1 greater than p 2H1: p1>p2

Your answer is correct.

(b) Determine the test statistic.

z0equals=nothing

(Round to two decimal places as needed.)
