A poll was taken this year asking college students if they considered themselves overweight. A similar poll was taken 5 years age. Five years age, a sample of 270 students showed that 120 considered themselves overweight. This year a poll of 300 students showed that 140 considered themselves overweight. At a 5% level of significance, test to see if there is any difference in the proportion of college students who consider themselves overweight between the two polls. What is your conclusion?

ABC Inc., began the year with 10,000 units in stock but finished with 5,000 units. It produced 45,000 units for the period. Its selling price is $12 per unit, variable manufacturing cost is $5 per unit, and variable selling is $3 per unit. Fixed manufacturing and selling costs are $100,000 and $72,000 respectively. The firm notes that variable cost per unit (both mfg and SGA) was the same this and the prior year. What is the income under variable costing?

2. Refer to the prior problem. The firm informs you that inventory values under absorption costing decreased by $39,000. Compute (Income as reported under variable costing - Income as reported under absorption costing), noting that it is change in FMOH between the opening and closing inventory accounts.

If a project has a cost of $10,000, expected net cash flows of $1500 a year for 12 years and you use a discount rate of 6%, what is the following:

1. Payback period (no application of discount rate)
2. Payback period (using discount rate)
3. NPV
4. IRR
5. Should the project be accepted?

If another project has a cost of $10,000 and has expected life of 8 years and it will generate $3000 a year should you accept the project if your boss says the cost of capital is 5%?

Assume the following sales data for a company:

If 2017 is the base year, what is the percentage increase in sales from 2017 to 2018?

Company projects the following sales for the first three months of the​ year: $14300 in January​;$ 10100, in February​;and $10,400 in March.

The company expects 60​% of the sales to be cash and the remainder on account. Sales on account are collected in the month of the sale and​ 50% in the following month. The Accounts Receivable account has a zero balance on January 1. Round to the nearest dollar.

Calculate how many barrels of oil to refine, for the 15th year, into gasoline. Use the following data and create a forecast model that will enable you to solve the problem, and then solve.

Given:

Period: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Demand: 1500, 2100, 1900, 2250, 2200, 3000, 2675, 3327, 3619, 3550

Given the following income data from a representative sample of a population in a certain year, what is its Gini index?

Of all freshman at a large college, 16% made the dean’s list in the current year. As part of a class project, students randomly sample 40 students and check if those students made the list. They repeat this 1000 times and build a distribution of sample proportions.

1. What is this distribution called?

2. Would you expect the shape of this distribution to be symmetric, right skewed, or left skewed? Explain your reasoning.

3 Find/calculate a measure of the variability of this distribution. 4. What is the formal name of the value that you computed in (c)?

5. Use the information above to construct a 95% confidence interval and interpret it using a full sentence.

6. What is the margin of error in your confidence interval? (Be sure to show a calculation to support your response.)

7. Suppose the students decide to sample again, this time collecting 90 students per sample. They build a new distribution of sample proportions. How will the variability of the new distribution compare to the variability of the distribution when each sample contained 40 observations.

- A stock expects to pay a year-end dividend of $2.50 a share (i.e., D₁ = $2.50); assume that last year’s dividend has already been paid). The dividend is expected to decline 5 percent a year, forever (i.e., g = -5%). The company’s expected and required rate of return is 12 percent. What is the current market price per share of this stock?

- The expected rate of return on the common stock of Northwest Corporation is 10 percent. The stock’s dividend is expected to grow at a constant rate of 6 percent a year. The stock currently sells for $55 a share. What is the next expected dividend per share (i.e., D₁) on this stock?

-  A share of preferred stock pays a quarterly dividend of $1.50. If the price of this preferred stock is currently $40, what is the nominal annual rate of return?

- Harper Manufacturing has realized the following annual sales dollar amounts:

                                             2016:                                                   $12,500,000

                                    2017:                                                   $16,000,000

                                    2018:                                                   $18,000,000

               Calculate the arithmetic average annual growth rate in sales dollars that Harper Manufacturing realized during the 2016 through 2018 time-frame.
