Answer:

The common problem i encounter mostly is the statistical modelling problem.

In this scenario we choose best combination of independent variables for the hypothesis testing. the independent variable shows the significant effect on dependent variable so we keep it in modelling.

My null hypothesis would be that there is no significant effect of independent variable on dependent variable.  for my alternative hypothesis there exist is significant effect of independent variable on dependent variable.

Explanation:

Solution

The common problem I face daily is the statistical modelling problem which is the selection of relevant independent variable for prediction modelling.

In this example to select the best combination of independent variables we use hypothesis testing. if the independent variable has significant effect on dependent variable then the independent variable shows the significant effect on dependent variable so we keep it in modelling. In this way the model gets improved.

Since there are always two variables or two categories. hence it has a two sample test.

The Hypothesis can be shown below:

Null hypothesis:

H0:There is no significant effect of independent variable on dependent variable.

Alternative hypothesis:

Ha: There is significant effect of independent variable on dependent variable.

If the inflation rate averages 3 percent over the next 8 years, the expected cost of services for any year in that time frame is
lys-0071 [83]

Answer:

The expected cost 8 years from now = $13.87

Explanation:

If the inflation rate averages 3 percent yearly over the next 8 years, the expected cost of services for any year in that time frame is given by

C (x) = K (1.03)ˣ

where

K = present cost = $10.95

x = time in years = 8

So, the expected cost of a haircut 8 years from now would be

C(x=8) = 10.95 (1.03)⁸ = $13.87

Hope this Helps!!!!

Sunny Co has a debt-to-equity ratio of 1.00, compared to the industry average of 0.80. Its competitor Carter Co., however, has a
ankoles [38]

Answer:

The answer is C.

Explanation:

Debt-to-equity ratio is an economical term that is used to express the balance between a companies total debt and its assets. It shows at what ratio the company's assets are funded by investors, stakeholders etc.

Since the industry average debt-to-equity ratio is 0.80 and the two companies have debt-to-equity ratios of 1.00 and 1.50 respectively, they are both over the average.

But with the higher ratio, Carter Co. has a higher financial risk compared to Sunny Co. and the industry average debt-to-equity ratio. So the correct answer is C.

I hope this answer helps.

Required information E12-3 Understanding the Computation of Cash Flows from Operating Activities (Indirect Method) [LO 12-2] [Th
kompoz [17]

Answer:

Net income = $320

Net cash flow from Operating activity = $145

Explanation:

The journal entries are shown below:

1. Cash A/c Dr $485

        To Service revenue A/c $485

(Being sales service is provided for cash)

2. Salary expense A/c Dr $165

   Outstanding salary expense A/c Dr $175

              To Salary and wages payable A/c  $340

(Being salary expense is recorded)

Salary and wages payable A/c  $340

       To Cash $340

(Being salary and wages are paid)

The net cash flow from operating activities would be

= Service revenue - salaries and wages payable

= $485 - $340

= $145

The net income would be

= Sales - salary expense

= $485 - $165

= $320

Cash flow from Operating activities under the indirect method  

Net income $320

Less: Decrease in salary payable - $175

Net Cash flow from Operating activities $145
