Question

Given two independent random samples with the following results:

n1=573, p^1=0.5

n2=454, pˆ2=0.6

Can it be concluded that the proportion found in Population 2 exceeds the proportion found in Population 1? Use a significance level of α=0.1α=0.1for the test.

Step 1 of 5: State the null and alternative hypotheses for the test.

Step 2 of 5: Compute the weighted estimate of p, p‾p‾. Round your answer to three decimal places.

Step 3 of 5: Compute the value of the test statistic. Round your answer to two decimal places.

Step 4 of 5: Determine the decision rule for rejecting the null hypothesis H0. Round the numerical portion of your answer to two decimal places.

Step 5 of 5: Make the decision for the hypothesis test (Reject or fail to reject null hypothesis)
