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.

Answer:

$48 will give Rick 2 sets of products combination that give him utility of 8.

At his utility-maximizing point, Rick's utility is 2* 8 = 16 utils.

Suppose that lenders want to receive a real rate of interest of 5 percent and that they expect inflation to remain steady at 2 p
Helga [31]

Answer:

7%

Explanation:

nominal interest rate = real interest rate + expected inflation rate

nominal interest rate = 5% + 2% = 7%

Usually the nominal interest rate has four major components:

  1. real interest rate: the net interest rate received by a lender or an investor
  2. inflation rate: the general rise in the prices of goods and services, as inflation increases, the purchasing power of a currency decreases
  3. liquidity risk premium: usually collateralized loans include a liquidity risk premium since not all assets can be easily converted to cash.
  4. credit risk: possibility of the borrower defaulting the loan

The condensed financial statements of Marks Company for the years 2017-2018 are presented below: Marks Company Comparative Balan
kirill115 [55]

Answer:

Marks Company

Computation of Financial Ratios:

(a) Current ratio at 12/31/18 =  Current Assets/Current Liabilities = $1,1350,000/$339,000 = 3.35

(b) Acid test ratio at 12/31/18 = (Current Assets - Inventory)/Current Liabilities =  $760,000/$339,000 = 2.24

(c) Accounts receivable turnover in 2018 = Net Credit Sales/Average Accounts Receivable = $2,420,000/$328,000 = 7.37 times

(d) Inventory turnover in 2018 = Sales/Average Inventory = $2,420,000/$357,000 = 6.77 times or every 54 days.

(e) Profit margin on sales in 2018:

i) Gross Profit Margin = Gross Profit/Sales x 100 = $778,000/$2,420,000 x 100 = 32%

ii) Net Profit Margin  = Net Income/Sales x 100 = $278,000/$2,420,000 x 100 = 11.49%

(f) Earnings per share in 2018 = Earnings or Net Income divided by outstanding number of shares = $278,000/152,100 = $1.82

(g) Return on common stockholders’ equity in 2018 = Net Income divided by Common Equity = $278,000/$1,961,000 x 100 = 14.18%

(h) Price earnings ratio at 12/31/18 = Market price per share divided by earnings per share = $80/$1.82 = $43.95

(i) Debt to assets at 12/31/18 = Total Debts/Total Assets = $744,000/$2,705,000 x 100 =  27%

(j) Book value per share at 12/31/18 = Shareholders' Equity divided by number of outstanding shares = $1,961,00/152,100 = $12.89

Explanation:

a) Current Ratio = Current Assets/Current Liabilities

Current Assets for 2018:

Cash $404,000

Accounts Receivable $356,000

Inventories $375,000

Total = $1,135,000

Current Liabilities for 2018:

Accounts Payable $339,000

Dividends Payable $0

Total = $339,000

This liquidity ratio measures the entity's ability to pay off its current obligations with its liquid assets.  Current assets are assets that can easily be turned to cash within the calendar year.

b) Acid Test Ratio is also a liquidity ratio that evaluates an entity's ability to pay off its current obligations with current assets when inventory is excluded.  Inventory is not regarded as very liquid, especially given the longer time it may take to turn it over to cash.

c) Accounts Receivable Turnover measures the effectiveness of the company to collect its receivables resulting from the credit sales.  It shows how sales on credit are managed by evaluating the credit policy, collection process, and customers' creditworthiness.  In quantitative terms, it measures how many times receivables are converted to cash in a period.

d) Inventory Turnover measures the number of times average inventory was turned over to sales within a period.  The average inventory is the beginning and ending inventories divided by 2.  It is very useful in inventory decisions, especially pricing, production or purchase, etc.

e) Profit margin on sales is the gross profit or net income expressed as a percentage of sales.  The Gross profit margin measures the ability of management to create profit from its sales revenue when compared with the costs of sales.  The net profit margin measures the ability of the management to create value for the stockholders after deducting all expenses for running the business.

f) Earnings per share:  This is a profitability ratio that compares the net income to the number of outstanding shares.

g) Return on common stockholders’ equity: This ratio measures the company's ability to generate returns for common stockholders.  It is measured as net income for common equity divided by the common stockholders' equity.

h) Price earnings ratio: This ratio expresses the dollar amount which an investor can invest in a company in order to earn a dollar income.  It is used to value investment in a company.

i) Debts to Assets: This is a financial leverage ratio that tells the percentage of assets or a company's resources that is financed by creditors.

j) Book value per share: This is a market value measure that shows the value of net assets (equity) divided by the outstanding shares.  It is not the same as the market value per share, which reflects investors sentiments.  The book value per share compares the book value of equity with the number of shares.  It is used by investors to gauge if a stock is undervalued or not.

Snowcat [4.5K]

If France had positive net exports last year, then it (A) sold more abroad than it purchased abroad and had a trade surplus.

<h3>What is trade surplus?</h3>
  • When focused simply on trade effects, a trade surplus indicates that a country's goods are in high demand on the global market, which raises the price of those items and leads to a direct strengthening of the home currency.
  • When exports surpass imports, the trade balance (surplus) is positive.
  • When exports are fewer than imports, the trade balance is negative (deficit).
  • When a country exports more goods than it imports, it has a trade surplus.
  • For example, if China exported $1 trillion in products while importing only $200 billion in goods, it would have an $800 billion trade surplus.

Therefore, if France had positive net exports last year, then it (A) sold more abroad than it purchased abroad and had a trade surplus.
