Determine whether a normal sampling distribution can be used for the following sample statistics. If it can be used, test the claim about the difference between two population proportions p₁ and p2 at the level of significance a. Assume that the samples are random and independent. Claim: P₁ P₂, α = 0.01 Sample Statistics: x₁ = 32, n₁ = 71, x₂ = 34, n₂ = 76 OA. Z= (Round to two decimal places as needed.) OB. The conditions to use a normal sampling distribution are not met. Calculate the P-value, if applicable. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. P= (Round to three decimal places as needed.) OB.
