Step 2

The method of standard deviation is similar to the population standard deviation.

Operations Management homework question answer, step 2, image 1

The standard deviation of the sample mean can be calculated by the following formula.

Operations Management homework question answer, step 2, image 2

On substituting the given value in the formula.

Operations Management homework question answer, step 2, image 3

Hence, the standard deviation for the sample mean is 0.60

Step 3

Ans 2:

(x-bar) is calculated by calculating the average of given numbers in a column and Range is calculated by subtracting the largest value from the smallest value.

Lanni Products is a start-up computer software development firm. It currently owns computer equipment worth $30,000 and has cash
Sonbull [250]

Answer:

a. Lanni takes out a bank loan. It receives $50,000 in cash and signs a note promising to pay back the loan over three years.

  • FINANCIAL ASSET CREATED: when the loan was received, a financial asset was created. Money is exchanged for a promissory note.

b. Lanni uses the cash from the bank plus $20,000 of its own funds to finance the development of new financial planning software.

  • REAL ASSET CREATED: when the software was developed, a real asset was created. Money was invested in developing the software.

c. Lanni sells the software product to Microsoft, which will market it to the public under the Microsoft name. Lanni accepts payment in the form of 2,500 shares of Microsoft stock.

  • FINANCIAL ASSET CREATED: when the software was traded, a financial asset was created. A real asset was traded in exchange for financial assets.

d. Lanni sells the shares of stock for $50 per share and uses part of the proceeds to pay off the bank loan.

  • FINANCIAL ASSET DESTROYED: when the loan is paid back, the financial asset (loan) ceases to exist. When the money is paid back to the bank, the loan and the promissory note cease to exist.

a-1. Prepare its balance sheet just after it gets the bank loan.

Lanni Products

Balance Sheet

After it got the bank loan

Assets:

Cash $70,000

Computer equipment $30,000

Total assets $100,000

Liabilities:

Shareholders's equity :

Paid in capital $50,000

Total shareholders's equity $50,000

Total liabilities and shareholders' equity $100,000

a-2. What is the ratio of real assets to total assets?

ratio of real assets to total assets = computer equipment / total assets = $30,000 / $100,000 = 30%

b-1. Prepare the balance sheet after Lanni spends the $70,000 to develop its software product.

Tamarisk, Inc. had a beginning inventory on January 1 of 293 units of Product 4-18-15 at a cost of $21 per unit. During the year
Radda [10]

Answer:

Tamarisk, Inc.

                                          FIFO         LIFO        AVERAGE-COST

Ending inventory            $13,788      $10,857           $12,303

Cost of goods sold        $47,576    $50,507          $49,062

Explanation:

a) Data and Calculations:

Date            Transaction              Units      Unit Cost         Total

January 1    Beginning inventory  293          $21             $6,153

Mar. 15        Purchase                    780         $24             18,720

July 20       Purchase                     488         $25            12,200

Sept. 4       Purchase                     683         $27              18,441

Dec. 2        Purchase                     195         $30              5,850  

Total          Goods available       2,439                          $61,364

                 Units sold                  1,950

                 Ending inventory        489

FIFO:

Ending inventory

      = 195 at $30 = $5,850

        294 at $27 = $7,938

Total 489  =          $13,788

Cost of goods sold = Cost of goods available for sale minus Cost of ending inventory = $61,364 - $13,788 = $47,576

LIFO:

Ending inventory:

293 at $21 =    $6,153

196 at $24 =     4,704

Total 489 =   $10,857

Cost of goods sold = $61,364 - $10,857 = $50,507

Weighted-Average Cost:

Weighted-average cost = Cost of goods available for sale/Units available for sale

= $61,364/2,439 = $25.16

Ending inventory = $12,303 (489 * $25.16)

Cost of goods sold = $49,062 (1,950 * $25.16)

b) The distinguishing factor among these inventory valuation methods is the assumption basis for their computations.  FIFO assumes that goods that first come into store are the first to be sold or First-in, First-out.  LIFO assumes that goods that are last in the store are the first to be sold, expressed as Last-in, First-out.  Lastly, the weighted average method uses the weighted average costs of inventories purchased at different times and prices to compute the cost of each unit.
