The Wall Street Journal reported that automobile crashes cost the United States $162 billion annually (The Wall Street Journal,

March 5, 2008). The average cost per person for crashes in the Tampa, Florida, area was reported to be $1599. Suppose this average cost was based on a sample of 50 persons who had been involved in car crashes and that the population standard deviation is σ = $600. What is the margin of error for a 95% confidence interval? Round your answer to two decimal places.

Answer:

Error = 166.308459

Explanation:

Given that,

Standard deviation (SD) = $600

Sample (n) = 50 persons

Error(E) = ?

For a 95% confidence interval,

Z-value from the z-table is 1.959963985

E=\frac{z\times SD}{\sqrt{n}}

E=\frac{1.959963985\times 600}{\sqrt{50}}

E=\frac{1,175.97839}{7.07106781}

         = 166.308459

Therefore, the margin of error for a 95% confidence interval is 166.308459.

Last year Dania Corporation's sales were $525 million. If sales grow at 10.5% per year, how large (in millions) will they be 8 y
Andru [333]

In 8 years, Dania Corporation's sales would be $936.33 million.

Solution:

Since last year sales = $525 million,

Let last year be Year 0

So, in year 0 = $525 million.

Sales grow = 7.5% per year,

Year 1,

525 x 1.075 = $564.375 million.

Year 2,

564.375 x 1.075 = $606.7 million

Year 3,

606.7 x 1.075 = $652.2 million

Year 4

652.2 x 1.075 = $701.12 million

Year 5

701.12 x 1.075 = $753.7 million

Year 6

753.7 x 1.075 = $810.23 million

Year 7

810.23 x 1.075 = $871 million

Finally in year 8

871 x 1.075 = $936.33 million

True [87]

Answer:

Net Income $23,588

Retained Earnings $140,088

Explanation:

To calculate the value of the retained earning at the end of the next year it's necessary to find the income of the current year and then deduct the dividends paid during the year, the remaining value adds to the retained earnings.

This value that we get of retained earnings at the end of the year, it's the value missing at the end of the year to explain the accounting equation of Assets = Liabilitites + Equity
