2. Change all of the numbers in the data area of your worksheet so that it looks like this: If your formulas are correct, you should get the correct answers to the following questions. (a) What is the Predetermined overhead rate? (Round your answer to 2 decimal places.) (b) By how much is the manufacturing overhead underapplied or overapplied? 3. Either print or make a copy of your worksheet in your workbook before proceeding. You will need to refer back to this worksheet. Change the estimated total amount of the allocation base to 59,000 machine-hours, but keep everything the same as in Requirement 2. The data area of your worksheet should now look like this: (a) By how much is the manufacturing overhead underapplied or overapplied? (b) Why is the amount of underapplied (overapplied) manufacturing overhead different from Requirement 2 above? (You may select more than one answer. Single click the box with the question mark to produce a check mark for a correct answers and double click the box with the question mark to empty the box for a wrong answers. Any boxes left with a question mark will be automatically graded as incorrect.) ? The change in the estimated total amount of the allocation base affected the predetermined overhead rate. ? The change in the estimated total amount of the allocation base affected the amount of manufacturing overhead applied. ? Actual manufacturing overhead cost differs from period to period. 4. Change the estimated total amount of the allocation base back to 63,000 machine-hours, so that the data area of you worksheet looks exactly the same as in Requirement 2 . Now change the actual manufacturing overhead cost from $358,600 to $351,900. The data area of your worksheet should now look like this: (a) By how much is the manufacturing overhead underapplied or overapplied? (b) Why is the amount of underapplied (overapplied) manufacturing overhead different from Requirement 2 above? (You may select more than one answer. Single click the box with the question mark to produce a check mark for a correct answers and double click the box with the question mark to empty the box for a wrong answers. Any boxes left with a question mark will be automatically graded as incorrect.) The predetermined overhead rate changed. ? The change in the actual manufacturing overhead cost directly resulted in a comparable change in the amount of underapplied
