Evaluate each of the following conclusions for correctness if an auditor selected a random sample of 100 items from a population of 2,000 and, based upon accurate statistical calculations, determined that the confidence interval was \($4,200\) \($1,500\) at the 90% confidence level:

a. The confidence limits are between \($2,700\) and \($5,700\) at a 90% confidence level.

b. There is a 5% statistical risk that the true population value is more than \($5,700.\)

c. If the auditor took a large number of additional samples, each with a sample size of 100 items, the point estimate would fall between \($2,700\) and \($5,700\) approximately 90% of the time.
