Question
Decide whether the normal sampling distribution can be used. If it can be used, test the claim about the population
proportion p at the given level of significance a using the given sample statistics.
Claim: p0.28; a=0.10; Sample statistics: p = 0.23, n = 100
Can the normal sampling distribution be used?
OA. Yes, because pq is greater than a = 0.10.
OB. No, because nq is less than 5.
OC. Yes, because both np and nq are greater than or equal to 5.
OD. No, because np is less than 5.
State the null and alternative hypotheses.
OA. Ho: p≥ 0.28
Ha p<0.28
OB. Ho p≤0.28
Ha: p>0.28
OC. Ho: p=0.28
H₂ p 0.28
OD. The test cannot be performed.
