The 95% confidence interval will be wider than the 90% confidence interval.

In statistics, the likelihood that a population parameter will fall between a set of values for a certain percentage of the time is referred to as a confidence interval. Analysts frequently employ confidence ranges that include 95% or 99% of anticipated observations. Therefore, it may be concluded that there is a 95% likelihood that the real value falls within that range if a point estimate of 10.00 with a 95% confidence interval of 9.50 - 10.50 is derived using a statistical model.

  • The level of certainty or uncertainty in a sampling process is measured by confidence intervals.
  • Additionally, they are employed in regression analysis and hypothesis testing.
  • To determine statistical significance, statisticians frequently combine confidence intervals with p-values.
  • 95% or 99% confidence levels are most frequently used in their construction.

HACTEHA [7]

Answer:

Instructions are listed below

Explanation:

Giving the following information:

June 1:

Inventory: 120 units for $5= $600

June 12:

Purchase: 370units for $6= $2,220

June 23:

Purchase: 200 units for $7= $1,400

June 30:

Ending Inventory 230 units

Units sold= 460

<u>Under FIFO method, the first units-in are the first to go out. Therefore, the ending inventory has the value of the last units purchased.</u>

<u />

Inventory= 200*7 + 30*6= $1,580

COGS= 120*5 + 340*6= $2,640

<u>Under LIFO method, the lasts units-in are the first out. </u>

Inventory= 120*5 + 110*6= $1,260

COGS= 260*6 + 200*7= $2,960

<u>Under the average cost method, we calculate an average buying price and then calculate the ending inventory and cost of goods sold:</u>

<u />

Average price= (5 +6 +7)/3= 6

Inventory= 230*6= $1,380

COGS= 460*6= $2,760

The highest ending inventory is from FIFO method.

A vice president of operations wants to evaluate the impact of reducing manufacturing expenses on the firm's return on assets. W
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.

likoan [24]

Complete Question:

Match the terms with the correct definitions.

Answer:

1. Fixed costs: Costs that do not change in total over wide ranges of volume.

2. Sensitivity analysis: Technique that estimates profit or loss results when conditions change.

3. Breakeven point: The sales level at which operating income is zero.

4. Margin of safety: Drop in sales a company can absorb without incurring an operating loss.

5. Sales mix: Combination of products that make up total sales.

6. Contribution margin: Net sales revenue minus variable costs.

7. Cost behavior: Describes how a cost changes as volume changes.

8. Variable costs: Costs that change in total in direct proportion to changes in volume.

9. Relevant range: The band of volume where total fixed costs and variable cost per unit remain constant.

Explanation:

It is required that each term are matched with their respective correct definitions. The terms are generally associated with business and sales management.

For instance, fixed costs are indirect costs that do not change in total over wide ranges of volume and irrespective of the level of output (goods and services) e.g rent, salaries, property tax, insurance, depreciation etc.

Also variable costs are costs that change in total in direct proportion to changes in volume of goods and services e.g sales commission, utility costs, raw materials costs, credit card fees, direct labour costs etc.

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed
patriot [66]

The number of books that will be produced such that the costs from the two methods be the same is 4668 units.

From the complete question, the total cost of the first equation will be:

= 8.25x + 65054

The total cost for the second equation will be:

= 19.50x + 12539

Then, we'll equate both equations together and this will be:

8.25x + 65054 = 19.50x + 12539

Collect like terms

19.50x - 8.25x = 65054 - 12539

11.25x = 52515

Divide both side by 11.25

11.25x/11.25 = 52515/11.25

x = 4668 units.

Therefore, the breakeven unit will be 4668 units.
