Question

A sample of size 30 was taken from a very large population in order to estimate a proportion, p. The sample was found to have a proportion of p = 0.2.

How many successes were found in this sample?

Can we use the apply the normal distribution to estimate pp in this situation?

Yes, the Z-normal distribution may be used.

Why or why not?

The sample size is less than 5% of the population size.
The number of successes or number of failures is less than 10.
The sample size is at least 5% of the population size.
The number of successes and number of failures is at least 10.
