1. n 2017, Nina contributes 11 percent of her $126,000 annual salary to her 401(k) account. She expects to earn a 10 percent before-tax rate of return. Assuming she leaves this (and any employer contributions) in the account until she retires in 25 years, what is Nina’s after-tax accumulation from her 2017 contributions to her 401(k) account? (Use Table 1, Table 2, Table 3, Table 4.) (Round your intermediate calculations and final answers to the nearest whole dollar amount. Round "Future value factor" to 4 decimal places.)
a. Assume Nina’s marginal tax rate at retirement is 30 percent.
|
b. Assume Nina’s marginal tax rate at retirement is 20 percent.
|
c. Assume Nina’s marginal tax rate at retirement is 40 percent.

Researchers at the Mayo Clinic found a significant association between hospital sound levels and patient healing (louder hospital sound level is associated with slower healing). Based on these findings, a new hospital installed a new flooring that is supposed to reduce the noise level in hospital corridors. Using α = 0.01, did the variance of noise level decrease? (use both methods) Problem 4: Mayors of nine communities started a watch program to reduce vandalism. The number of vandalism incidents before and after starting the watch program was collected for each community. Does the data collected show that the watch program was effective? (use both methods)

4. Write out the pseudocode for when Merge-Sort is stable based on the information given below:
Comparision Based Stable Sorts such as Merge Sort maintain stability by ensuring that Element A[ j ] comes before A[ i ] if and only if A[ j ] < A[ i ], here i, j are indices and i < j. The relative order is preserved if A[ i ] comes before A[ j ].
Mergesort is stable, provided its implementation employs the comparison ≤ in merging. Indeed, assume that we have two elements of the same value in positions i and j, i < j, in a subarray before its two (sorted) halves are merged. If these two elements are in the same half of the subarray, their relative ordering will stay the same after the merging because the elements of the same half are processed by the merging operation in the FIFO fashion. Consider now the case when A[ i ] is in the first half while A[ j ] is in the second half. A[ j ] is placed into the new array either after the first half becomes empty (and, hence, A[ i ] has been already copied into the new array) or after being compared with some key k > A[ j ] of the first half. In the latter case, since the first half is sorted before the merging begins, A[ i ] = A[ j ] < k cannot be among the unprocessed elements of the first half. Hence, by the time of this comparison, A[ i ] has been already copied into the new array and therefore will precede A[ j ] after the merging operation is completed.

Capwell Corporation uses a periodic inventory system. The company's ending inventory on December 31, 2011, its fiscal-year end, based on a physical count, was determined to be $326,000. Capwell's unadjusted trial balance also showed the following account balances: Purchases, $620,000; Accounts payable; $210,000; Accounts receivable, $225,000; Sales revenue, $840,000.
The internal audit department discovered the following items:
1. Goods valued at $32,000 held on consignment from Dix Company were included in the physical count but not recorded as a purchase.
2. Purchases from Xavier Corporation were incorrectly recorded at $41,000 instead of the correct amount of $14,000. The correct amount was included in the ending inventory.
3. Goods that cost $25,000 were shipped from a vendor on December 28, 2011, terms f.o.b. destination. The merchandise arrived on January 3, 2012. The purchase and related accounts payable were recorded in 2011.
4. One inventory item was incorrectly included in ending inventory as 100 units, instead of the correct amount of 1,000 units. This item cost $40 per unit.
5. The 2010 balance sheet reported inventory of $352,000. The internal auditors discovered that a mathematical error caused this inventory to be understated by $62,000. This amount is considered to be material.
6. Goods shipped to a customer f.o.b. destination on December 25, 2011, were received by the customer on January 4, 2012. The sales price was $40,000 and the merchandise cost $22,000. The sale and corresponding accounts receivable were recorded in 2011.
7. Goods shipped from a vendor f.o.b. shipping point on December 27, 2011, were received on January 3, 2012. The merchandise cost $18,000. The purchase was not recorded until 2012.
Required:
1. Determine the correct amounts for 2011 ending inventory, purchases, accounts payable, sales revenue, and accounts receivable.
2. Calculate cost of goods sold for 2011.
3. Describe the steps Capwell would undertake to correct the error in the 2010 ending inventory. What was the effect of the error on 2010 before-tax income?
