Lindsey is a Procurement Manager for School Manufacturing (RM). She is considering a proposal from her supplier Livingston Electronics (LE). LE has proposed to supply an electrical component, SCM-305, that is used by RM for one of its industrial products. Up until now RM has manufactured the component in-house. After hearing about LE’s proposal, RM’s production manager indicated that it might be worth further consideration, so Lindsey decided to perform a cost analysis.

The RM accounting department provided Lindsey with the following unit cost information for the in-house manufacturing of SCM-305:

Direct Labor $ 7.00

Direct Material                                                9.00

Factory O/H Variable 3.00

Factory O/H Fixed                                            4.00

                     Total Unit Cost                         $23.00

The LE proposal is to provide SCM-305 at a unit price of $22.00. If the decision is to buy from LE, the SCM-305 production equipment at RM would become idle.

Which of the following is the correct Continue to Make or Buy analysis and conclusion?

Group of answer choices

Make = $23.00; Buy = $19.00 therefore, buy it

Make = $23.00; Buy = $22.00 therefore, buy it

Make = $20.00; Buy = $22.00 therefore, continue to make it

Make = $19.00; Buy = $22.00 therefore, continue to make it

Albany High School is planning a field trip for senior students. They expected 100 students to participate in the trip but eventually 130 students join the trip. They planned to charge each student a price of $25 for the trip and spend an expense of $20 per student for the trip. Then, they find that the expense of the filed trip goes up to $30 per student, and they have to increase the price for each student to $40.

Budget Actual

Number of students 100 130

Revenue per student $25 $40

Expense per student $20 $30

(1) What is the expense variance? Is it favorable or unfavorable? How would this variance affect the balance of the budget (aka: the profit)? (Hint: Homework 6 templates might be useful for this question, but you don’t need to follow the templates. No need to consider Quantity (input) in this question.)

(2) What is the revenue variance? Is it favorable or unfavorable? How would this variance affect the balance of the budget (aka: the profit)? (Hint: Homework 6 templates might be useful for this question, but you don’t need to follow the templates. No need to consider the Mix in this question.)

(3) What is the total variance (revenue variance and expense variance together)? Is it favorable or unfavorable? How would this variance affect the balance of the budget (aka: the profit)?

You have just been accepted to nursing school. As a requirement, you have to have a tuberculosis (TB) test as well as a hepatitis B recombinant vaccine. The nurse who administers the TB skin test explains that if significant swelling occurs around the injection site, you will need to have chest x-rays to determine if you are infected with Mycobacterium tuberculosis. On the morning of the second day after the skin test, you awake to find your arm red and swollen in an area about the size of a quarter around the site of the test. It is also tender to the touch. Now you are really worried. Could you have TB?

1. Why does the reaction to the skin test take 36-48 hours to show up? Explain. 2. If you have a tuberculosis infection, why doesn’t the whole body, or at least the respiratory tract, react when the antigen is injected during this diagnostic test?

Richard is a retired solicitor. His wife Tracy is a retired school teacher. Both wish to remain active and they invest in a gift shop that is to be managed by their daughter Alice, who is aged 35. They form a partnership of three called “Alice's Gift Shop”. Richard and Tracy contributed $40,000 each to fund the purchase of the shop. The partnership agreement provides: • Both Richard and Tracy are to receive interest at the rate of 10% p.a. on their capital contribution of $40,000. • Alice will receive a salary of $25,000 for the management of the shop, as well as superannuation contributions of $6,000. • A car will be leased by the business and provided to Alice. • All profits and losses are to be shared equally between the three partners. The accounts for this income year show the following: Income ($) Sales (excluding GST) 240,000 Expenses ($) Cost of goods sold 130,000 Interest on capital paid to Richard and Tracy 8,000 Salary to Alice 25,000 Superannuation to Alice 6,000 Lease payments on car (excluding GST) 7,000 Other deductible operating expenses (excluding GST) 14,000 The leased car was used 80% of the time for business and 20% of the time for private purposes. Required: With reference to the facts above: A.Calculate the net income of the partnership. B.Show the allocation of net income to each of the three partners. C.You must refer to relevant legislation and/or case law in your answer. (as per ATO)

They want to make monthly contributions to another account that pays 11% with annunal compunding.

What is the monthly contribution to reach 140k at 15 years old

A school psychologist is interested in determining if children with attention deficit disorder (ADD) learn better if English literature is read to them rather than having them read the material themselves. A random sample of 10 sixth graders with ADD is selected and divided into two groups of 5 each. One of the groups has a story read to them (Listening Group) and the other reads the story themselves (Reading Group). A quiz on the story is given after each group has finished reading or hearing the story. The following scores were obtained with 20 being a perfect score. Please analyze this data using a two-tailed test at the α = .05 level.

The confidence interval for this study was calculated as .42 to 6.78. What is the appropriate interpretation of the confidence interval?

In a study of high-achieving high school graduates, the authors of a report surveyed 837 high school graduates who were considered "academic superstars" and 436 graduates who were considered "solid performers." One question on the survey asked the distance from their home to the college they attended.

Assuming it is reasonable to regard these two samples as random samples of academic superstars and solid performers nationwide, use the accompanying data to determine if it is reasonable to conclude that the distribution of responses over the distance from home categories is not the same for academic superstars and solid performers. Use

α = 0.05.

State the null and alternative hypotheses.

a). H₀: The proportions falling into the distance categories are not all the same for the two student groups.
H_a: The proportions falling into the distance categories are the same for the two student groups.

b). H₀: Student group and distance of college from home are not independent.
H_a: Student group and distance of college from home are independent.  

c). H₀: The proportions falling into the distance categories are the same for the two student groups.
H_a: The proportions falling into the distance categories are not all the same for the two student groups.

d). H₀: Student group and distance of college from home are independent.
H_a: Student group and distance of college from home are not independent.

Calculate the test statistic. (Round your answer to two decimal places.)
χ² =  

What is the P-value for the test? (Round your answer to four decimal places.)
P-value =  

What can you conclude?

Do not reject H₀. There is not enough evidence to conclude that there is an association between student group and distance of college from home.

Reject H₀. There is convincing evidence to conclude that the proportions falling into the distance categories are not all the same for the two student groups.   

Do not reject H₀. There is not enough evidence to conclude that the proportions falling into the distance categories are not all the same for the two student groups.

Reject H₀. There is convincing evidence to conclude that there is an association between student group and distance of college from home.

Psychologists conducted a survey of 300 high school students and their attitudes towards vaping. One of the variables of interest was the response to the question, “Are you confident that you can resist peer pressure from your friends to vape?” Each response was measured on a 7-point likert scale, from 1=“Absolutely not” to 7=“Absolutely yes.”, as part of a survey given to the students after attending a presentation warning of the hazards of vaping. The psychologists reported a sample mean response of 4.75 and a sample standard deviation of 1.69 for this test item. Suppose that it is known that the true mean response to this question for students who do not attend the anti-vaping presentation is μ=4.3 for this question.

Conduct a test of hypothesis to determine whether the sample of students who attended the presentation are less likely to succumb to peer pressure. Use α =.05

b.) What is the p-value associated with your findings?

c.) If you were to instead conduct this test using α=.01, does your conclusion change? Explain why or why not
