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 p, at the level of significance
Assume that the
samples are random and independent.
Claim: p, *P2, a = 0.01
Sample Statistics: x, = 39, n, = 65, x, = 37, n, = 60
Determine whether a normal sampling distribution can be used.
The samples are random and independent. A normal sampling distribution
V be used becausen,p=,n,q=, np=, and n,q=O:

State the null and alternative hypotheses, if applicable.
O A. Ho: P, 2P2
H: P1 <P2
O B. Ho: P1 = P2
H: P, *P2
OC. Ho: P, SP2
H: P1 > P2

Determine whether a normal sampling distribution can be used for the folklowing sample statistics. If it can be used, test the claim about the difference between two population proportions p, and pa at the level of significance a. Assume that the
samples are random and independent.
Claim: p, #Pz, =0.01

(Round to three decimal places as needed.)
O B. The conditions to use a normal sampling distribution are not met.
State the conclusion of the hypothesis test, if applicable. Choose the correct answer below.
O A. Since P<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 H. There is enough evidence at the a = 0.01 level of significance to support the claim.
O C. Since P>a, fail to reject Ho. There is not enough evidence at the a = 0.01 level of significance to support the claim.
O D. Since P>a, reject Hp: There is enough evidence at the a =0.01 level of significance to support the claim.
O E. The conditions to use a normal sampling distribution are not met.
