- Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the difference between two population proportions p 1 and p 2 at the given level of significance alpha using the given sample statistics. Assume the sample statistics are from independent random samples. Claim: p 1 equalsp 2 , alpha equals0.10 Sample statistics: x 1 equals148 , n 1 equals168 and x 2 equals91 , n 2 equals214 Can a normal sampling distribution be used? Yes No Identify the null and alternative hypotheses. Choose the correct answer below. A. Upper H 0 : p 1 equalsp 2 Upper H Subscript a : p 1 greater thanp 2 B.
