Answer:

a=0.2 -0.674*0.3=-0.00235

So the value that separates the bottom 25% of data from the top 75% is -0.00235.  

Explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:

X \sim N(0.2,0.3)  

Where \mu=0.2 and \sigma=0.3

For this part we want to find a value a, such that we satisfy this condition:

P(X>a)=0.75   (a)

P(X   (b)

Both conditions are equivalent on this case. We can use the z score again in order to find the value a.  

As we can see on the figure attached the z value that satisfy the condition with 0.25 of the area on the left and 0.75 of the area on the right it's z=-0.674. On this case P(Z<-0.674)=0.25 and P(z>-0.674)=0.75

If we use condition (b) from previous we have this:

P(X  

P(z

But we know which value of z satisfy the previous equation so then we can do this:

z=-0.674

And if we solve for a we got

a=0.2 -0.674*0.3=-0.00235

So the value that separates the bottom 25% of data from the top 75% is -0.00235.

alisha [4.7K]

Answer:

Trend- % change in sales =  34.64%

Explanation:

<em>Trend analysis entails determining the performance of a business over time by comparing its performance data from one period to another. The aim of trend analysis is to identify the behavior of a set of ratios over a period of time by comparing them across different years.</em>

To determine the trend for a particular data, we use the formula below

% Change in variable =

(Current year figure - Previous year figure)/Previous year figure × 100

DATA

Current year figure  for sales (2017) - 450,000

Previous year figure for sale (2016) - 688,500

% change in sales =   (450,000 -688,500)/688,500 × 100 = 34.64%

% change in sales =  34.64%

This implies that the company made sales in 2017 which is 34.64% less than that made in 2016

asambeis [7]

Answer:

The correct answer is A) $2.800

Explanation:

Using the straight-line method to depreciate, the calculation to find the depreciation tax shield is the following:

  1. Finding the depreciable cost: Depreciable cost = purchase price ($70,000) - salvage value ($14,000) = $56,000
  2. Finding the depreciation per year: Depreciation/year = \frac{Depreciable cost (56,000)}{Asset useful life (7 years)} = $8000
  3. Finally, the depreciation tax shield for 2018: Depreciation tax shield = Dep/year ($8,000) * tax rate (0,35) = $2,800

A difference in quantity of materials used on two comparable jobs may be caused by a.employee carelessness b.poor quality materi
Elodia [21]

Answer: d.All of these choices are correct.

Explanation:

All the above can result in different quantities of materials being used for comparable jobs.

Employee Carelessness can cause more material to be used if they fail to adequately measure the Requirements of a job. If they are also careless in the usage of the material, there will be wastage and therefore a larger use of materials.

Poor Quality Materials can also result in different quantities being used because for instance, more material could be required to do something that a stronger material could have easily done.

Inadequately trained Employees is a major reason for Material Wastage. If employees are not trained by seasoned people who know how to reduce wastage, that knowledge could take time to come to them. If they were adequately trained however, they can master the tricks on wastage avoidance and limit discrepancies in the amount of materials used per comparable jobs.

You are given the following information for O'Hara Marine Co.: sales = $75,500; costs = $35,200; addition to retained earnings =
pshichka [43]

Answer:

O'Hara Marine Co.

Depreciation Expense is:

$13,903

Explanation:

a) Data and Calculations:

sales = $75,500;

costs = $35,200;

addition to retained earnings = $9,580;

dividends paid = $8,420;

interest expense = $2,620;

tax rate = 23 percent

Net Income:

addition to retained earnings = $9,580;

dividends paid = $8,420

Total net income = $18,000

Pre-tax Income = $18,000/0.77 = $23,377

Income tax (23%) of $23,377 = $5,377

After Tax Income = $18,000 ($23,377 - 5,377)

Depreciation:

sales = $75,500

costs = $35,200

Gross profit =     $40,300

Less interest         (2,620)

Less net income  (23,777)

Depreciation =    $13,903
