Answer:
e) Counters of inventory should be those who are responsible for the inventory.
Explanation:
Having different people do the physical counting of inventory guarantees the integrity of the count. The staff in charge of inventory are probably aware of any variances as they conduct regular checks. Having different people count eliminates the possibility of number manipulation by the staff responsible for the stock.
Before a stock count, all operations should be halted. Items received during the stock count should be separated and not counted. There should be a document giving instructions to staff to ensure consistency.
As a measure of internal control, all stocks should be identified with a numbered tag. The supervisor should ensure proper tagging has been done. Where possible, counters will be organized in teams of two so that each item goes through two counts. Assign groups to count items which are not in their direct responsibility. Should there be a variance, a separate team should be allowed to counter check.
Answer:
(a) E(X) = 3
(b) Var(X) = 12.1067
Explanation:
(a) E[X]
E[X]T = E[X]T=A + E[X]T=B + E[X]T=C
= (2.6 + 3 + 3.4)/3
= 2.6 (1/3) + 3(1/3) + 3.4(1/3)
= 2.6/3 + 1 + 3.4/3
= 3
(b) Var (X) = E[X²]−(E[X])²
Recall that if Y ∼ Pois(λ), then E[Y 2] = λ+λ2. This implies that
E[X²] = [(2.6 + 2.6²) + (3 + 3²) + (3.4 + 3.4²)]/3
= (9.36 + 12 + 14.96)/3
= 36.32/3
= 12.1067
Var(X) = E[X²]−(E[X])²
= 12 - 3²
= 12.1067 - 9
= 3.1067

Answer:
d.$18,900
Explanation:
Gross Profit is the net of Sales value and production cost in the period for the units sold. Under absorption costing all the direct and indirect costs incurred in the production of products are included in the total production cost. As the cost is available for 100 units produced we need to calculate the cost of 90 unit and deduct this cost from the sales value to determine the gross profit and then deduct the operating expenses to calculate the operating income.
Sales (90 units) $90,000
Less: Production costs:
Direct materials ( $40,000 x 90/100 ) $36,000
Direct labor ( 20,000 x 90/100 ) $18,000
Variable factory overhead ( 2,000 x 90/100 ) $1,800
Fixed factory overhead ( 7,000 x 90/100 ) <u>$6,300</u>
Total Production cost <u>($62,100)</u>
Gross Profit $27,900
Less Operating expenses:
Variable operating expenses $8,000
Fixed operating expenses $1,000
<u>($9,000)</u>
Operating Income <u>$18,900</u>
