Answer:

Hence the null hypothesis is not rejected.

We conclude that productivity objective (in dollars) is not better than $75,000 per employee.

Explanation:

Single sample t-test ( upper tail test)

H_0: \mu = 75000\\H_1: \mu > 75000

N=20

Mean =75500

Sd=18968.117

t = \frac { (\bar x - \mu)} {\frac {s} {\sqrt{n}}}\\\\t = \frac{(75500-75000)}{\frac{18968.117}{\sqrt{20}}}\\t=0.1179

DF= 20-1=19

Table value of t at 0.05 level of significance =1.7291

Calculated t=0.1179 < table value 1.7291

The null hypothesis is not rejected

We conclude that productivity objective (in dollars) is not better than $75,000 per employee

The ________ created a multimember executive, whereas the ________ created a one-person executive
4vir4ik [10]
<span>The looser interpretation of the law created a multimember executive whereas the strict interpretation created a one-person executive. This filling in of the blanks creates an appropriate and meaningful sentence. Laws may be open to various interpretations. If "person" was thought to be a singular physical person, that would give rise to a strict interpretation for the purposes of the law and a "one-person executive". Operational definitions are important, and "person" could be interpreted as an "entity" or a "collective" in which case the looser interpretation of a law would be at play to create the "multi-member executive".</span>

frosja888 [35]

Available Options Are:

a. Cost of Goods Sold

b. Net Profit Margin

c. None of these

d. Asset Turnover

Answer:

Option B. Net Profit Margin

Explanation:

The increase or decrease in cost of Goods sold can not tell whether the return on assets has increased or decreased becuase it would only tell that the expense are decreased or increased not the profit. Which means it only tells one side of the story hence Option A is incorrect.

Option B is correct because it talks about the profit. If the manufacturing cost has been decreased then the it must increase the profit. Because if the profits has increased then the return on asset will increase. Hence the Option B is correct here.

Option D is incorrect because asset turnover formula is:

Asset Turnover = Sales / Total Assets

The decrease in manufacturing cost will not increase the sales because sales and total assets are independent of manufacturing expenses hence the Option D is incorrect.

There is an issue with this trial as one of the soft drinks going level may affect the rating of the members. As indicated by Malhotra (2010) the most widely recognized strategy utilized for testing is combined correlation. This can be utilized by the members for successful examination.  

The perplexing variable in the investigation incorporates the measure of time that went between the tasting of various soft drinks. The temperature of the soft drink additionally indicates the inclination of the members.

Explanation:

Is necessary to consider different amount of suppliers and evaluate the cost. We will choose the number of suppliers which offers a lower cost.

  • EMV1 = cost of shutdown*super event risk + cost of shutdown*unique event risk + cost of managing supplier = 480000*.02 + 480000*0.05+16000 = 9600 + 24000 + 16000 = $ 49600

  • EMV2 = cost of shutdown*super event risk + cost of shutdown*unique event risk of each supplier*unique event risk of each supplier + cost of managing 2 suppliers = 480000*.02 + 480000*0.05*.05+16000*2 = 9600 + 1200 + 16000*2 = $ 42800

  • EMV3 = cost of shutdown*super event risk + cost of managing 3 suppliers = 480000*.02 + 480000*0.05*.05+16000*2 = 9600 + 16000*3 = $ 57600

Based on the EMV value, the best choice is to use Two suppliers
