The four dimensions are simultaneously active within the thinker and incorporate both general and specific statistical thinking tendencies. Describe the four statistical reasoning/thinking dimensions that are used in statistical investigation.

* Give and describe a concrete example of how the four-step method was applied in a managerial decision-making process. Please apply the four dimensions of statistical reasoning from Wild and Pfankuch .

* Why is having a representative sample rather than a random sample not more crucial for drawing accurate conclusions about a diverse population?

Nutech Corp. is expecting the following cash flows—$79,000, $112,000, $164,000, $84,000, and $242,000—over the next five years.

Alja [10]

Answer:

$429,560

Explanation:

Present value will be calculated through the PV formula,

$PV = \frac{C1}{1+r} + \frac{C2}{(1+r)^{2} } + \frac{C3}{(1+r)^{3}} + \frac{C4}{(1+r)^{4}} + \frac{C5}{(1+r)^{5}}$

r = 15%

C1 = $79,000 ,C2 = $112,000 ,C3 = $164,000 ,C4 = $84,000 ,C5 = $242,000

Substituting the values in the formula,

$PV = \frac{79,000}{1.15} + \frac{112,000}{(1.15)^{2} } + \frac{164,000}{(1.15)^{3}} + \frac{84,000}{(1.15)^{4}} + \frac{242,000}{(1.15)^{5}}$

PV = 68,695.66 + 84,688 + 107,838 + 48,030.2 + 120,338.14

PV = $429,560

The present value of the cash flows of Nutech Corp. over the next five years is $429,560.

What does "2/10" mean, with respect to "credit terms of 2/10, n/30"?

ANEK [815]

a. a discount of 2 percent will be allowed if the invoice is paid within 10 days of the invoice date.

So for example if the bill is $100 "2/10 net 30" and you pay within 10 days, you get a 20 cent discount and the balance is $9.80. If you pay in 30 days, the full 10 dollars is due.

Use the following information to answer this... Use the following information to answer this question. Windswept, Inc. 2010 Inco

prisoha [69]

Answer:

The Quick ratio: 0.86:1

Explanation:

The question is completed first as follows:

Windswept, Inc. 2009 and 2010 Balance Sheets ($ in millions) 2009 2010 2009 2010 Cash $ 270 $ 300 Accounts payable $ 1,530 $ 1,485 Accounts rec. 1,080 980 Long-term debt 1,140 1,340 Inventory 1,930 1,755 Common stock $ 3,420 $ 3,370 Total $ 3,280 $ 3,035 Retained earnings 680 930 Net fixed assets 3,490 4,090 Total assets $ 6,770 $ 7,125 Total liab. & equity $ 6,770 $ 7,125 What is the quick ratio for 2010?

Solution:

The requirement is to use the given information to calculate Windswept Inc's Quick ratio for 2010.

Quick ratio: this represents the ability of an organisation's short term liquidity to cover and cater for its short term obligation. Basically, it looks at the ratio of the current assets of an organisation (those that can be quickly converted to cash) to meet the current liabilities.

The formula for quick ratio= Current Assets - Inventory / Current Liabilities

Windswept's quick ration = Cash + Accounts receivable / Accounts Payable (all for 2010)

= $300 + 980 / $1, 485

= $1,280/$1,485

= 0.86:1

This means that the current asset of the company can only cover its current obligations up to about 86%. This is the quick ratio.

You are considering two investment alternatives. The first is a stock that pays quarterly dividends of $0.32 per share and is tr

MrMuchimi

Answer:

The 1-year HPR for the second stock is 12.84%. The stock that will provide the better annualized holding period return is Stock 1.

Explanation:

For First stock

Total dividend from first stock = Dividend per share * Number quarters = $0.32 * 2 = $0.64

HPR of first stock = (Total dividend from first stock + (Selling price after six months - Initial selling price per share)) / Initial selling price = ($0.64 + ($31.72 - $27.85)) / $27.85 = 0.1619, or 16.19%

Annualized holding period return of first stock = HPR of first stock * Number 6 months in a year = 16.19% * 2 = 32.38%

For Second stock

Total dividend from second stock = Dividend per share * Number quarters = $0.67 * 4 = $2.68

Since you expect to sell the stock in one year, we have:

Annualized holding period return of second stock = The 1-year HPR for the second stock = (Total dividend from second stock + (Selling price after six months - Initial selling price per share)) / Initial selling price = ($2.68+ ($36.79 - $34.98)) / $34.98 = 0.1284, or 12.84%

Since the Annualized holding period return of first stock of 32.38% is higher than the Annualized holding period return of second stock of 12.84%. the first stock will provide the better annualized holding period return.

The 1-year HPR for the second stock is 12.84%. The stock that will provide the better annualized holding period return is Stock 1.
