Answer:

The Confidence Interval(CI) is calculated as (0.043, 0.257).

The steps and expanation is shown below.

Explanation:

The formula for a Confidence Interval(CI) for a population proportion is given as

p + z*[Sqrt(p(1 - p))/n]

Or

p - z*[Sqrt(p(1 - p))/n],

p is the sample proportion, n is the sample size, and z* is the appropriate value from the standard normal distribution for your desired confidence level. The following table shows values of z* for certain confidence levels.

For the 98% Confidence Interval, z*–value = 2.33

p = 9/60 = 0.15, confidence level z* = 2.33( From the standard table)

0.15 + 2.33[Sqrt(0.15(1 - 0.15))/60]

OR

0.15 - 2.33[Sqrt(0.15(1 - 0.15))/60]

0.15 + 0.107 or 0.15 - 0.107

Confidence Interval is

(0.043, 0.257)

Answer:

= (0.043 , 0.257)

Explanation:

p = 9/60 = 0.15

Z score for 98% confidence interval = Z0.01 = 2.33

The Confidence interval = (p + Z0.01 * sqrt(p * (1 - p) / n))

= (0.15 + 2.33 * sqrt(0.15 * (1 - 0.15) / 60))

= (0.15 + 0.107)

= (0.043 , 0.257)

The owner of a bicycle repair shop forecasts revenues of $188,000 a year. Variable costs will be $57,000, and rental costs for t
Umnica [9.8K]

Answer:

Revenues=$188,000

Less: Variable Costs=$57,000

Less: Rentals=$37,000

Earnings before depreciation and tax=$94,000

Less: Depreciation =$17,000

Earnings before tax=$77,000

Less: Tax40%=$30,800

Net Income=$46,200

a) Dollars in minus dollars out

Dollars in = Revenues = $188,000

Dollars out = Variable cost + Rentals + Tax = $57,000 + $37,000 + $30,800 = $124,800

Operating cash flow = $188,000 - $124,800 = $63,200

b) Adjusted accounting profits

Operating cash flow = Net income + Depreciation = $46,200 + $17,000 = $63,200

c) Add back depreciation tax shield

Operating cash flow = Earnings before depreciation and tax x (1 - tax rate) + Depreciation tax shield

or, Operating cash flow = $94,000 x (1 - 0.40) + $17,000 x 40% = $63,200

Yes, all the results are same.

The most recent financial statements for Cardinal, Inc., are shown here: Income Statement Balance Sheet Sales $23,500 Assets $12
finlep [7]

Answer:

$20,370.5

Explanation:

Net Profit Margin = Net Profit / Sales= 5,168 / 23500 = 0.219915 = 21.99%

Dividend Payout Ratio = Dividends / Net profit = $1,560/$5,168 = 0.3018576 = 30.19%

Increase in Assets = Total Assets / Current Sales * Change in Sales

Increase in Assets = 121,000 /23,500 * (28,300-23,500)

Increase in Assets = 5.1489362 * 4800

Increase in Assets = $24714.89

Increase in Current Liabilities = Current Liabilities / Current Sales * Change in Sales = 0

Earnings Retained = Revised sales * Net profit margin * (1- dividend payout ratio)

Earnings Retained = $28,300 * 21.99% * (1 - 30.19%)

Earnings Retained = $28,300 * 0.2199 * 0.6981

Earnings Retained = $4344.39497

Earnings Retained = $4344.39

External Financing Needed = Increase in Assets - Increase in Current Liabilities - Earnings Retained

External Financing Needed = $24714.89 - $0 - $4344.39

External Financing Needed = $20,370.5

Hyu Corporation bases its predetermined overhead rate on the estimated labor-hours for the upcoming year. At the beginning of th
Free_Kalibri [48]

Answer:

The predetermined overhead rate for the recently completed year was $25.33

Explanation:

The formula to compute the predetermined overhead rate is shown below:

Predetermined overhead rate = (Total estimated manufacturing overhead) ÷ (estimated direct labor-hours)

where,

Total estimated manufacturing overhead = Estimated total fixed manufacturing overhead + estimated variable manufacturing overhead rate × estimated labor hours

= $1,230,440 + $3.12 × 55,400 hours

= $1,230,440 + $172,848

= $1,403,288

Now put these values to the above formula  

So, the rate would equal to

= $1,403,288 ÷ 55,400 hours

= $25.33

Romashka [77]

Answer:

A. Volatility

Explanation:

Volatility refers to high level of fluctuations with little or no consistency. It also refers to the variation in an activity with no constancy.

In the given case, Andrew keeps on swapping jobs within a short duration of time, and in varied fields of little similarity. This conveys a high degree of volatility in Andrew's work habits since he is unable to stick to one job or a field of job.

The changes in his employment structure reveal a pattern of high level of deviations, fluctuations referred to as Volatility.
