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 p, and p2 at the level of significance . Assume that the samples are random and independent. Claim: P1 # P2, a = 0.01 Sample Statistics: X1 = 37, n, =66, X2 = 39, n2 = 71 Determine whether a normal sampling distribution can be used. The samples are random and independent. A normal sampling distribution be used because n, p = . n q= , n2p = , and n2a =]. Round to two decimal places as needed.) State the null and alternative hypotheses, if applicable. O A. Ho: P1 SP2 Ha: P1 > P2 OB. Ho: P1 2 P2 Ha: P1 a, fail to reject Ho . There is not enough evidence at the a = 0.01 level of significance to support the claim. O B. Since P > a, reject Ho. There is enough evidence at the a = 0.01 level of significance to support the claim. O C. Since P
