THE AUDITING CASE. The auditor for a large corporation routinely monitors cash disbursements. As part of thisprocess, the auditor examines check request forms to determine whether they have been properly approved. Improper approval can occur in several ways. For instance, the check may have no approval, the check request might be missing, the approval might be written by an unauthorized person, or the dollar limit of the authorizing person might be exceeded. a. Last year the corporation experienced a 5 percent improper check request approval rate. Because this was considered unacceptable, efforts were made to reduce the rate of improper approvals. Letting p be the proportion of all checks that are now improperly approved, set up the null and alternative hypotheses needed to attempt to demonstrate that the current rate of improper approvals is lower than last year’s rate of 5 percent.
