Consider a population proportion p = 0.22. [You may find it useful to reference the z table.]

a. Calculate the standard error for the sampling distribution of the sample proportion when n = 18 and n = 60? (Round your final answer to 4 decimal places.)

b. Is the sampling distribution of the sample proportion approximately normal with n = 18 and n = 60?

c. Calculate the probability that the sample proportion is between 0.18 and 0.22 for n = 60. (Round "z-value" to 2 decimal places and final answer to 4 decimal places.)
