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 α using the given sample statistics.
Claim:p≠0.26;α=0.01;
Sample statistics:p=0.19,n=200
Sample statistics:p=0.19,n=200
Can the normal sampling distribution be used?
Yes, because pq is greater than α=0.01.
No, because nq is less than 5.
No, because np is less than 5.
Yes, because both np and nq are greater than or equal to 5.
