Steven, a newly graduated chef, is interested in establishing a family business. To supplement the equipment you already have, you need to purchase a commercial refrigerator that costs $ 20,000 and is classified for depreciation purposes as a 3-year MACRS property. The asset is estimated to have a resale value at the end of its six-year useful life of $ 3,000. Operational and maintenance expenses are expected to be $ 1,500 the first year and will increase $ 300 annually from the second year. Uniform annual income of $ 10,000 is expected. In addition, to acquire this alternative, she needs to make a loan of $ 10,000 that will be repaid in four years according to the amortization schedule shown in the table.

Generate the table detailing the after-tax analysis of this investment alternative. Apply an effective tax rate of 30%. You must show your calculations in detail to get credit.

After completing your analysis, briefly explain what measure of merit (decision criteria) you would use to explain to the chef if this is a good investment. Write a sentence with your recommendation. Assume a 15% MARR after tax.

You have just sat through an informative lecture in your managerial accounting class about the net present value (NPV). However, one of your classmates leaned over to tell you that he is still unclear about this theory and would like for you to provide a summary of what this concept is all about and why it is so important. Explain to your classmate the key arguments for using NPV over other capital investment approaches and why it is the preferred method for making decisions about long-term investment opportunities.

Further to the legalization of Cannabis in Canada, the Ontario Ministry of Transportation (OMT) is preparing an advertising campaign to discourage impaired driving due to the use of cannabis products. The campaign will target the most dangerous combinations of THC levels and time since last intake on driving competencies. As a recent Telfer graduate with a passion for statistics, you’ve been hired by the OMT to manage this project with the assistance of a research agency. You recruit 60 individuals and assign them randomly to 4 different treatment groups of interest. Subjects must consume a certain quantity of cannabis and then go to a virtual simulator room after a certain period of time to test their driving abilities on a scale totaling 30 points. Score data for the different treatment groups can be found in the data below at the end of the questions

a) This study consists of what kind of experiment? Describe its main components and explain how it differs from an observational study.

b)Make a side-by-side boxplot of the data and explain if the similar variance and the nearly normal conditions for conducting an ANOVA seem to be satisfied.

c) In addition to a side-by-side boxplot, what other graphs can you use to check if the assumptions/conditions for using an ANOVA are satisfied? (Note: you don’t need to produce these graphs; just explain how you would produce them.)

d)Calculate the sample variance for each treatment group and then use it to calculate the pooled variance manually. Check to see if your pooled variance agrees with the MSE displayed on the partial ANOVA table in part e) below.

e) Fill in manually the correct values for the missing values in the ANOVA table below. Show your computations (maximum of 2 decimal places).

f) Using the one-way ANOVA in e) above, test if there is a significant difference in the true mean score between the 4 treatment groups using the critical value approach and a 5% significance level. Make sure you follow all the steps for hypothesis testing indicated in the Instructions section, show your computations, and state the business significance of your conclusion.

g) Use the Bonferroni multiple comparison method to determine which population means differ at α = 0.05. Show your computations.

h) Perform a Kruskal-Wallis non-parametric test to determine whether there is a difference among the four-intake group (treatment group) scores. Use a 5% significance level and the critical value approach. You can use Excel or Minitab for your calculations but remember to show all the steps of your hypothesis test. Is your conclusion consistent with your results in f) above?

Analysis of daily output by a factory employee shows that, on average, the number of units per hour produced after t hours on the job can be modeled by y = 70t + 0.5t 2 − t 3 where 0 ≤ t ≤ 8.

(a) Thinking about the context of this problem, explain why t-values in this model might be restricted to values between t = 0 and t = 8.

(b) Find all the critical numbers for this function. Hint: You may want to use the quadratic formula or a quadratic program on your calculator as part of this calculation.

(c) Which critical number(s) that you found in part (b) make sense in this problem? Explain your reasoning in the context of this problem.

(d) For the critical number(s) you stated in part (c), explain, in the context of this problem, what this critical number tells you.

1. Let’s assume you have a bag of balls (5 red and 5 black). You roll a six-sided dice and then select a ball from the bag.
   1. What is the probability you roll a five on the die and then select a red ball?
2. You are playing blackjack with no other players (i.e. cards are dealt immediately with no one else receiving cards). What is the probability you get a K, Q, J, or 10 on the first card followed by an ace on the second card? (No replacement)
3. The Powerball Lottery requires you to select 5 numbers between 1 and 69 and 1 number between 1 and 26. What is the probability of selecting ALL numbers correct? (Please show your work).
