A survey of several 10 to 12 year olds recorded the following amounts spent on a trip to the mall: $14.73,$18.13,$11.20,$14.89,$18.78,$21.08,$17.26 Construct the 99% confidence interval for the average amount spent by 10 to 12 year olds on a trip to the mall. Assume the population is approximately normal.

Step 1 of 4 : Calculate the sample mean for the given sample data. Round your answer to two decimal places.

Fredonia Inc. had a bad year in 2013. For the first time in its history, it operated at a loss. The company’s income statement showed the following results from selling 75,800 units of product: Net sales $1,455,360; total costs and expenses $1,754,400; and net loss $299,040. Costs and expenses consisted of the following. Total Variable Fixed Cost of goods sold $1,206,500 $782,900 $423,600 Selling expenses 426,000 79,600 346,400 Administrative expenses 121,900 50,900 71,000 $1,754,400 $913,400 $841,000 Management is considering the following independent alternatives for 2014. 1. Increase unit selling price 28% with no change in costs and expenses. 2. Change the compensation of salespersons from fixed annual salaries totaling $198,500 to total salaries of $39,900 plus a 5% commission on net sales. 3. Purchase new high-tech factory machinery that will change the proportion between variable and fixed cost of goods sold to 50:50.

I) Calculate the break even point for 2014.

II) Compute the break even point in dollars under each of the alternative courses of action.

A. Increasing selling price

B. Change in compensation

C. Purchase new machinery

Yakahoma Corp has 80.000 common stocks. At the end of a profitable year it decides to pay $2 cash dividend and 5 percent stock dividend. Current stock price is $12. How much will retained earnings reduce after cash and stock dividends distributed? *

Bruin Inc. will have earnings of $15 million next year and is projected to grow at a constant rate of 6 percent forever. All earnings are paid out as dividends to shareholders.

The company plans to launch a new project three years from now that will cost $10 million. The project will increase the firm's annual earnings by a constant $8.3 million every year forever starting one year later (i.e. 4 years from now).

What is the market value of the company stock? The discount rate is 10.6 percent.

Select one:

a. $192 million

b. $394 million

c. $138 million

d. $377 million

e. $50 million

The table shows the mid-year populations (in millions) of five countries in 2015 and the projected populations (in millions) for the year 2025.

 for the population of each country by letting

(b) You can see that the populations of Country D and Country E are growing at different rates. What constant in the equation 

y = ae^bt

 gives the growth rate? Discuss the relationship between the different growth rates and the magnitude of the constant.

The constant b determines the growth rate. The greater the rate of growth, the smaller the value of b.The constant a determines the growth rate. The greater the rate of growth, the greater the value of a.    The constant b determines the growth rate. The greater the rate of growth, the greater the value of b.The constant a determines the growth rate. The greater the rate of growth, the smaller the value of a.

What is the present value of an investment that pays $200 every other year forever if the first cash flow occurs in two years? What is the value when the first cash flow occurs in one year? The opportunity cost of capital is 12% per year.

Consider a project with a 6-year life. The initial cost to set up the project is $1,200,000. This amount is to be linearly depreciated to zero over the life of the project. You expect to sell the equipment for $240,000 after 6 years. The project requires an initial investment in net working capital of $120,000, which will be recouped at the end of the project.

You estimated sales of 63,000 units per year at a price of $160 each. The variable cost per unit is estimated to be $128 and fixed costs are $240,000 per year.

You expect unit sales, prices, variable and fixed costs to be within 15% of your estimates.

The required return is 12% and the tax rate is 34%.
