Question

Anyone?

anonymous · Answer

Compute the mean and standard deviation of the sampling distribution of p
State the relationship between the sampling distribution of p and the normal distribution

anonymous · Answer

In order to assume normality, the following must be true: np>10 and n(1 – p)>10.

Are those the conditions?

anonymous · Answer

Yes, those are conditions of the normal approximation, np>10 and n(1-p)>10 where n is the sample size and p is the probability of the desired event occurring
