Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the difference between two population proportions p₁ and p2 at the given level of significance a using the given sample statistics. Assume the sample statistics are from independent random samples. Claim: Sample statistics: Can a normal sampling distribution be used? No Yes Identify the null and alternative hypotheses. Choose the correct answer below. OA. Ho: P₁ P2 Ha: P₁ = P2 B. Ho: P₁ = P2 Ha: P₁ P2 C. Ho: P₁ = P2 Ha: P₁ P2 P₁ = P₂, α = 0.10 x₁ = 94, n₁ = 161 and x₂ = 58, n₂ = 203 D. Ho: P₁ P2 Ha: P₁ = P₂2 O E. A normal sampling distribution cannot be used, so the claim cannot be tested. Find the critical values. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. A. The critical values are - - Zo= and Z₁ = (Round to two decimal places as needed.) B. A normal sampling distribution cannot be used, so the claim cannot be tested. Find the standardized test statistic. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. Z= (Round to two decimal places as needed.)
