Assume the Conduct a test at the = 0.01 level of significance by determining a) the null and altemative hypotheses samples were obtained independently from a large population using simple random sampling. Test whether pl > p2. The sample data are x1 = 122, n,-255, x2 = 134, and n2 = 306. (a) Choose the correct null and alternative hypotheses below. A. H0: p1 =p2 versus H1 : p1 p2 0 D. Ho: p1 =p2 versus H1: p1 #p2 Click to select your answer and then click Check Answer Clear All Check Answer

Explanation / Answer

The statistical software output for this problem is:

Two sample proportion summary hypothesis test:
p1 : proportion of successes for population 1
p2 : proportion of successes for population 2
p1 - p2 : Difference in proportions
H0 : p1 - p2 = 0
HA : p1 - p2 > 0

Hypothesis test results:

Hence,

a) Null and Alternative Hypotheses: Option C is correct.

b) Test statistic = 0.96

c) P - value = 0.1687

Do not reject Ho; there is not sufficient evidence to conclude that p1 > p2
