Part B - Internal Control Testing Memo Date: May 15, 2017 To: Wheelz Co. Prepared by: Fahmida Mustafa Reference: A-1 Subject: Observations on test of control performed by auditor. Based on the review of documents provided, my observations are as follows: i) It is not acceptable to directly use the same transactions and sample size for the first two tests of controls, while the estimated population deviation rate is different for both controls. I think that sample size of 58 transactions which are randomly chosen would be appropriate for the first test of controls based on the moderate importance and the tolerance and 1% estimated deviation allocated. For the second test of controls with the difference in the estimated deviation, the sampile size for this test increases to 77 (according to the Attribute table: for 2% of estimated population deviation rate and 8% tolerable deviation rate for control deemed moderately important).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
