In each of Exercises, we have given the number of successes and the sample size for a simple random sample from a population. In each case, do the following tasks.

a.Determine the sample proportion.
b.Decide whether using the one-proportion z-interval procedure is appropriate.
c.If appropriate, use the one-proportion z-interval procedure to find the confidence interval at the specified confidence level.
d.If appropriate, nd the margin of error for the estimate of p and express the confidence interval in terms of the sample proportion and the margin of error.

x = 16, n = 20, 90% level
