3. The cations on an exchangeable site of a 40 g soil were displaced by repeatedly washing by a salt and found to be 40 mg Ca+2, 11.5 mg Na+1, 39 mg K+1, 12 mg Mg+2, and 9 mg Al+3. The pH of the soil was 5.0. Calculate the CEC (cmolc/kg), percentage base saturation (PBS) and percent acidic saturation (PAC) per kg of the soil.

4. A give soil has a CEC of 12.50 cmol of charge per kg of soil. If 70%, 15%, 10% and 5% of the CECis occupied by Ca+2, K+1, Mg and Na+1 , respectively, calculate the weight (grams) of Ca, K, Mg and Na in the soil.

5. A given soil contains the following colloids: 1.0% humus (CEC=200), 30% kaolinite (CEC=5), 5%smectite (montmorillonite) (CEC=80), 10% illite (CEC=20), 5% mica (CEC=70) and 49% sesquioxides (CEC=2). Calculate the CEC of the soil? Which colloids contributed the most and which contributed the least? (All CEC are in molc/kg soil).

6. Calculate the amount of pure CaCO3that could theoretically neutralize the H+ in one-year acid rain if a 1-hectare (ha) site received 200 mm of rain per year and the average pH of the rain was 5.0.

7. Calculate the pH and pOH of a soil with the following H+ concentrations: (a) 0.0000001M (b) 0.00001M (c) 0.005M? Which soil is relatively most acidic? Most basic?

You have just started a new job and your employer has enrolled you in KiwiSaver.

This is the first time you have been enrolled in KiwiSaver and you decide not to “opt out”.

You are interested in estimating how much your KiwiSaver fund could be worth when you retire.

You make the following assumptions:

• You have just turned 30 and will retire in exactly 35 years when you are 65.

• Your salary is $50,000 this year and you expect this to increase by 3% every year.

• You can choose to contribute either 3% or 8% of your salary into your KiwiSaver fund each year. https://www.kiwisaver.govt.nz/already/contributions/you/amount/

• Your employer must contribute 3% of your pay into your KiwiSaver fund each year. https://www.kiwisaver.govt.nz/already/contributions/employers/ You can ignore any tax implications and assume your account receives the full 3%. (KIWI SAVER ACC)

• You will be entitled to the annual member tax credit of $521.43 which will be credited into your KiwiSaver fund at the end of every year. https://www.kiwisaver.govt.nz/new/benefits/mtc/

• Your KiwiSaver fund will invest in a diversified portfolio of assets to earn a return on your investment. Of course, there is uncertainty around the actual annual rate of return that your fund will earn over the 35 years but you decide that 6% and 12% represent a good range of potential rates of return to conduct your analysis on.

• Regardless of the return earned, the manager of your KiwiSaver fund will charge a management fee of 1.0% at the end of each year, based on the opening balance of your fund each year.

• You will make no withdrawals or additional contributions (other than those mentioned above) to your fund until you retire in 35 years.

• For simplicity, assume that all contributions to your KiwiSaver fund are made once per year, at the end of the year. The first lot of contributions will be made in one year from today.

Construct a spreadsheet that will allow you to answer the following questions on Canvas.

Consider the following information on Huntington Power Co.

Debt: 4,000, 7% semiannual coupon bonds outstanding, $1,000 par value, 18 years to maturity, selling for 102 percent of par; the bonds make semiannual payments.

Preferred Stock: 10,000 outstanding with par value of $100 and a market value of 105 and $10 annual dividend.

Common Stock: 84,000 shares outstanding, selling for $56 per share, the beta is 2.08

The market risk premium is 5.5%, the risk free rate is 3.5% and Huntington’s tax rate is 32%.

Huntington Power Co. is evaluating two mutually exclusive project that is somewhat riskier than the usual project the firm undertakes; management uses the subjective approach and decided to apply an adjustment factor of +2.1% to the cost of capital for both projects.

Project A is a five-year project that requires an initial fixed asset investment of $2.4 million. The fixed asset falls into the five-year MACRS class. The project is estimated to generate $2,050,000 in annual sales, with costs of $950,000. The project requires an initial investment in net working capital of $285,000 and the fixed asset will have a market value of $225,000 at the end of five years when the project is terminated.

Project B requires an initial fixed asset investment of $1.0 million. The marketing department predicts that sales related to the project will be $920,000 per year for the next five years, after which the market will cease to exist. The machine will be depreciated down to zero over four-year using the straight-line method (depreciable life 4 years while economic life 5 years). Cost of goods sold and operating expenses related to the project are predicted to be 25 percent of sales. The project will also require an addition to net working capital of $150,000 immediately. The asset is expected to have a market value of $120,000 at the end of five years when the project is terminated.

Use the following rates for 5-year MACRS: 20%, 32%, 19.2%, 11.52%, 11.52%, and 5.76%

Please show your work.

1. What is the appropriate discount rate for project A and project B (Risk adjusted rate)?

In a recent year, according to the Bureau of Labor Statistics, the median number of years that wage and salary workers had been with their current employer (called employee tenure) was 3.5 years. Information on employee tenure has been gathered since the early 1950's using the Current Population Survey (CPS), a monthly survey of 50,000 households that provides information on employment, unemployment, earnings, demographics, and other characteristics of the U. S. population. With respect to employee tenure, the questions measure how long workers had been with their current employer, not how long they plan to stary with their employer.

Employee Tenure of 20 workers

4.1, 2.3, 3.5, 4.6, 3.1, 1.2, 3.9, 2.1, 1.0, 4.5, 3.2, 3.4, 4.1, 3.1, 2.8, 1.4, 3.4, 4.9, 5.7, 2.6

A) A congressional representative claims that the median tenure for workers from the representative's district is less than the national median tenure of 3.5 years. Thae claim is based on the representative's data shown above. Assume that the employees were randomly selected.

1) How would you test the representative's claim?

2) Can you use a parametric test, or do you need a nonparametric test? Why?

3) State the null and alternative hypothesis.

4) Test the claim using alpha = 0.05. What can you conclude? Show your work, the process that you used, and the result.

This was my prompt, and I'm not quire sure what to do.

1. Circle:

Implement a Java class with the name Circle. It should be in the package edu.gcccd.csis.

The class has two private instance variables: radius (of the type double) and color (of the type String).

The class also has a private static variable: numOfCircles (of the type long) which at all times will keep track of the number of Circle objects that were instantiated.

Construction:

A constructor that constructs a circle with the given color and sets the radius to a default value of 1.0.

an integer method size(), that returns 0, if all member variables are null, 1 either of the two member variables contains a value other than null, and 2, if both, the rectangle and circle contain values other than null.

Pargo Company is preparing its budgeted income statement for 2017. Relevant data pertaining to its sales, production, and direct materials budgets are as follows.

Sales. Sales for the year are expected to total  1,100,000 units. Quarterly sales are  22%,  24%,  25%, and  29%, respectively. The sales price is expected to be $ 41 per unit for the first three quarters and $ 47 per unit beginning in the fourth quarter. Sales in the first quarter of 2018 are expected to be  15% higher than the budgeted sales for the first quarter of 2017.

Production. Management desires to maintain the ending finished goods inventories at  20% of the next quarter’s budgeted sales volume.

Direct materials. Each unit requires  2 pounds of raw materials at a cost of $ 9 per pound. Management desires to maintain raw materials inventories at  10% of the next quarter’s production requirements. Assume the production requirements for first quarter of 2018 are  510,000 pounds.

Pargo budgets  0.3 hours of direct labor per unit, labor costs at $ 11 per hour, and manufacturing overhead at $ 17 per direct labor hour. Its budgeted selling and administrative expenses for 2017 are $ 6,558,000.

Calculate the budgeted total unit cost. (Round answer to 2 decimal places, e.g. 12.25.)

Prepare the budgeted multiple-step income statement for 2017. (Ignore income taxes.)

I don’t understand this. Last year [year 1], we decided to drop our highest-end Red model and only produce the Yellow and Green models, because the cost system indicated we were losing money on Red. Now, looking at the preliminary numbers, our profit is actually lower than last year and it looks like Yellow has become a money loser, even though our prices, volumes, and direct costs are the same. Can someone please explain this to me and maybe help me decide what to do next year?

Robert Dolan

President & CEO

Dolan Products

Dolan Products is a small, family-owned audio component manufacturer. Several years ago, the company decided to concentrate on only three models, which were sold under many brand names to electronic retailers and mass-market discount stores. For internal purposes, the company uses the product names Red, Yellow, and Green to refer to the three components.

Data on the three models and selected costs follow:

This year (year 2), the company only produced the Yellow and Green models. Total overhead was $625,400. All other volumes, unit prices, costs, and direct labor usage were the same as in year 1. The product cost system at Dolan Products allocates manufacturing overhead based on direct labor hours.

Required:

a. Compute the product costs and gross margins (revenue less cost of goods sold) for the three products and total gross profit for year 1. (Do not round intermediate calculations. Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places.)

b. Compute the product costs and gross margins (revenue less cost of goods sold) for the two remaining products and total gross profit for year 2. (Do not round intermediate calculations. Negative amounts should be indicated by a minus sign. Round your answers to 2 decimal places.)
     

c. Should Dolan Products drop Yellow for year 3?   

1. For a particular scenario, we wish to test the hypothesis H₀ : p = 0.48. For a sample of size 50, the sample proportion p̂ is 0.42. Compute the value of the test statistic z_obs. (Express your answer as a decimal rounded to two decimal places.)

2. Which of the following is a valid alternative hypothesis for a one-sided hypothesis test about a population proportion p?

A. p = 0.6

B. p < 0

C. p ≠ 0.7

D. p > 0.3

3. Suppose that the sample proportion p̂ is used to construct a confidence interval for the population proportion p. Assuming that the value of p̂ is fixed, which of the following combinations of confidence levels and sample sizes yield the the widest confidence interval (that is, one with the largest range of values)?

A. 95% confidence level, n = 500

B. 95% confidence level, n = 50

C. 99% confidence level, n = 50

D. 99% confidence level, n = 500

4. Which of the following statements about a confidence interval is NOT true?

A. A confidence interval of size α indicates that there is a probability of α that the parameter of interest falls inside the interval.

B. A confidence interval is generally constructed by taking a point estimate plus or minus the margin of error.

C. A confidence interval is often more informative than a point estimate because it accounts for sampling variability.

D. A confidence interval provides a range of plausible values for a parameter based on the sampling distribution of a point estimator.

5. For a test of H₀ : p = p_{0 vs.} H₁ : p < p₀, the value of the test statistic z _obs is -0.87. What is the p-value of the hypothesis test? (Express your answer as a decimal rounded to three decimal places.)

6. A pilot survey reveals that a certain population proportion p is likely close to 0.37. For a more thorough follow-up survey, it is desired for the margin of error to be no more than 0.03 (with 95% confidence). Assuming that the data from the pilot survey are reliable, what sample size is necessary to achieve this? (Express your answer as an integer, rounded as appropriate.)​​​​​​​

7. Suppose that you are testing whether a coin is fair. The hypotheses for this test are H₀: p = 0.5 and H₁: p ≠ 0.5. Which of the following would be a type II error?

A. Concluding that the coin is not fair when in reality the coin is not fair.

B. Concluding that the coin is fair when in reality the coin is fair.

C. Concluding that the coin is not fair when in reality the coin is fair.

D. Concluding that the coin is fair when in reality the coin is not fair.
