NEED ASAP

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.
