Question

A Gallup poll to survey the top concerns of Americans was conducted. Suppose that 566 women and 465 men were independently and randomly selected and that 322 women and 172 men chose the state of the economy as their biggest concern. Can we conclude that the proportion of women ( p1 ), choosing the state of the economy as their biggest concern, exceeds the proportion of men ( p2 )? Use a significance level of α=0.1 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, pˆ1p^1 and pˆ2p^2. Round your answers to three decimal places.

Step 3 of 6 :

Compute the weighted estimate of p, 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 H0H0. Round the numerical portion of your answer to three decimal places.

Step 6 of 6 :

Make the decision for the hypothesis test.
