Given two independent random samples with the following results:
n1=195
x1=30
n2=408
x2=144
Can it be concluded that there is a difference between the two population proportions? Use a significance level of α=0.02 for the test.
Step 1 of 6:
State the null and alternative hypotheses for the test.
Step 2 of 6:
Find the values of the two sample proportions, pˆ1 and pˆ2. Round your answers to three decimal places.
Step 3 of 6:
Compute the weighted estimate of p, p‾. Round your answer to three decimal places.
Step 4 of 6:
Compute the value of the test statistic. Round your answer to two decimal places.
Step 5 of 6:
Determine the decision rule for rejecting the null hypothesis H0. Round the numerical portion of your answer to two decimal places.
Step 6 of 6:
Make the decision for the hypothesis test.
