Answer:
True cost of the microwave is in 99% confidence interval: 
Explanation:
Relevant data:

As we want to know the 99% confidence interval, the significance level is:

We need to estimate a confidence interval by a two tailed normal bell. Then we have:

The z-value for a probability of 0.005 in a normal standard distribution is 2.576
Confidence interval is given by;:


True cost of the microwave is in 99% confidence interval: 
Answer:
Incremental loss of Spock = $19,800
Incremental profit of Uhura = $12,300
Incremental profit of Sulu = $94,200
Explanation:
Note: See the attached excel for the determination the incremental profit or loss that each of the three joint products.
In the attached excl file, the following formulae are used:
a. Incremental sales value = Sales value of processed product - Sales value at split off point
b. Incremental profit (loss) = Incremental sales value - Costs to process further
Answer:
Price to be paid now = $52.89
Explanation:
<em>The Dividend Valuation Model is a technique used to value the worth of an asset. According to this model, the worth of an asset is the sum of the present values of its future cash flows discounted at the required rate of return. </em>
T<em>he stock would be held for just a period, hence we would use the single period return model. This is given as follows:</em>
Price now = D/(1+r) + P×(1+r)
Dividend , r - rate of return, P -year-end price of stock
Dividend = 4.35, r-16%, P- 57
Price = 4.35/(1.16) + 57/(1.16)= $52.89
Price to be paid now = $52.89
Answer:
The contribution margin per unit is $5.1
Explanation:
The contribution margin per unit is the amount from selling price per unit after deducting all the related variable costs per unit. This is the amount that each product contributes towards covering the fixed costs.

<u>Contribution margin per unit:</u>
Selling price per unit 18.7
<u>Less : Variable cost per unit</u>
Direct material (7.05)
Direct labor (3.5)
Variable manufacturing Overhead (1.65)
Sales commission (1.00)
Variable Admin expense <u> (0.40)</u>
Contribution margin per unit 5.1
<span>Working for a mental health agency, it is next to impossible to access information. Our agency is required by law to maintain all client records for 7 years in a secured area (limited access by Executive Director & Director of Operations, No access by employees). After 7 years they are to be disposed of properly. Our agency shreds our documents personally as to not allow a private company to do so, hence there is no breach of confidentiality. Then a private company (document disposal company) removes the shredded documentation for destruction. So it would be impossible (or at least, improbable) to obtain access to our organization information through dumpster diving.</span>
