22. Suppose that the sample proportion p^ is used to construct a confidence interval for the population proportion p. Assuming that the value of p^is fixed, which of the following

combinations of confidence levels and sample sizes yield the the widest confidence interval (that is, one with the largest range of values)? 95% confidence level, n = 50 95% confidence level, n = 500 99% confidence level, n = 50 99% confidence level, n = 500
