A psychologist wanted to know if students in her class were more likely to cheat if they were low achievers. She divided her 60 students into three groups (low, middle, and high) based on their mean course score on the previous three course-testings. She then asked them to rate how likely they were to cheat on an course-testings if the opportunity presented itself with very limited chance for consequences. The students rated their desire to cheat on a scale ranging from 1-100, with lower numbers indicating less desire to cheat.

Two men, A and B, who usually commute to work together decide to conduct an experiment to see whether one route is faster than the other. The men feel that their driving habits are approximately the same, so each morning for two weeks one driver is assigned to route I and the other to route II. The times, recorded to the nearest minute, are shown in the following table. Using this data, find the 98%98%confidence interval for the true mean difference between the average travel time for route I and the average travel time for route II.

Let d=(route I travel time)−(route II travel time)d=(route I travel time)−(route II travel time). Assume that the populations of travel times are normally distributed for both routes.

This is a written, statistical report, not simply a collection of different types of Excel output. It is not necessary to include the formulas you used or a copy of the dataset. When answering the questions, make sure to include any relevant statistics and/or the results of your calculations. Like any other written report, you will want to start with an introductory paragraph or problem statement and finish with a conclusion that summarizes the information presented.

1. Use descriptive statistics to summarize the data.

2. Develop a 95% confidence interval estimate of the mean age of unemployed individuals in Philadelphia.

3. Conduct a hypothesis test to determine whether the mean duration of unemployment in Philadelphia is greater than the national mean duration of 14.6 weeks. Use a .01 level of significance. What is your conclusion?

4. Is there a relationship between the age of an unemployed individual and the number of weeks of unemployment? Explain.

The following data give the number of hours 5 students spent studying and their corresponding grades on their midterm exams.

Step 1 of 5 : Calculate the sum of squared errors (SSE). Use the values b0=76.2307b0=76.2307 and b1=3.7404b1=3.7404 for the calculations.

Step 2 of 5 : Calculate the estimated variance of errors, s^2e. .

Step 3 of 5 : Calculate the estimated variance of slope, s^2b1 .

Step 4 of 5 : Construct the 90% confidence interval for the slope. Lower point and Upper points

Step 5 of 5 : Construct the 99% confidence interval for the slope. Lower point and Upper point

3-19 Multiproduct breakeven point (LO 5) Andrew Sinclair operates a lawn care business. He offers customers a choice of two services. The first service, basic lawn care, includes mowing and trimming of all lawn areas. Andrew bills these customers $30 per hour, and his variable cost for providing this service is $22 per hour. Andrew also offers deluxe lawn care services, which includes flower bed maintenance in addition to basic lawn care. He bills his customers $60 per hour for this service, and his variable cost for providing this service is $28 per hour. Andrew currently spends 1 hour of his time providing deluxe lawn care services for every 4 hours of basic lawn care services. Andrew also incurs $140,800 in fixed costs per year running his business.

Required

a.What is Andrew's profit equation?

b.How many hours of each service type must Andrew provide in a year to break even?

c.Andrew believes that with a little persuasion, he could convert many of his basic lawn care customers to the deluxe service. If he is able to convert enough customers so that he spends an equal amount of time providing basic and deluxe services, how many hours will he need to work to break even?

Westerville Company reported the following results from last year’s operations:

[The following information applies to the questions displayed below.]

Three different companies each purchased trucks on January 1, Year 1, for $50,000. Each truck was expected to last four years or 200,000 miles. Salvage value was estimated to be $5,000. All three trucks were driven 66,000 miles in Year 1, 42,000 miles in Year 2, 40,000 miles in Year 3, and 60,000 miles in Year 4. Each of the three companies earned $40,000 of cash revenue during each of the four years. Company A uses straight-line depreciation, company B uses double-declining-balance depreciation, and company C uses units-of-production depreciation.

Answer each of the following questions. Ignore the effects of income taxes.

b-1. Calculate the net income for Year 4.
b-2. Which company will report the lowest amount of net income for Year 4?

Which company will report the lowest amount of net income for year 4?
