Question 1

As part of the fight to slow the progression of the COVID-19 pandemic, many jurisdictions have introduced policies to promote and enforce physical distancing, isolation/quarantine, limit social gatherings, and limit in-person business to essential services only, and other practices such as encouraging the use of face masks while in public. Similarly, universities and many businesses have migrated the bulk of their operations to online and remote operations and services. We’ve all experienced that at York University, work and non-work aspects of our lives. For your answer to Question 1, use your recent personal experiences to explore how these changes have impacted communication effectiveness. You may use examples from your recent York University experiences, recent work-related examples, or other recent personal examples that help you illustrate any changes that have happened. Consider a wide range of content from our course materials on communication. Ensure to articulate your arguments clearly and provide support for your claims, using and applying relevant concepts.

Sparky, Inc. presented the following select balance sheet accounts for Plant, Property & Equipment as well as Intangibles as of December 31, 2018:

The following information was reported in Sparky’s 10K filing as of December 31, 2018:

The equipment was purchased for $420,000 on October 1, 2017. It has an expected service life of 10 years and $32,000 salvage value. Sparky uses the Double-Declining Balance method for this class of asset.

The patent was acquired on January 1, 2018 and at that time had an estimated remaining useful life of 10 years.

During 2019, the following transactions and events may have affected Sparky’s long-lived assets:

Using the above information, answer each of the following questions:

a.

Determine the amount of the Impairment Loss (if any) Sparky would report for the Equipment as of December 31, 2019:

b.Assume that early in 2020, Sparky determined that the equipment will only remain productive through December 31, 2021 and changed to the straight-line method for this asset. The salvage value was determined to be $10,075. Determine Depreciation Expense (if any) Sparky would record for this equipment as of December 31, 2020:

Audubon Advisors is a volunteer student organization that uses business skills they’ve learned in their MBA program to advise local charity groups about business decisions. One charity group is planning to make and sell cutting boards at a major cooking show. The boards cost $6 each to make and will sell for $20 each. The boards will be made by volunteers at the show and all materials not used can be returned. That is, the group will make only the number of boards it can actually sell. The cooking show allows three options for groups selling at the show:

A. Pay a fixed booth fee of $5,600

B. Pay a fee of $3,800 plus 10% of all revenue from the boards sold at the show

C. Pay 25% of all revenues from boards sold at the show.

1. Compute the CM per board under each of the three options.

2. Compute the breakeven point in number of boards for each of the three options.

3. Which payment plan has the lowest risk of loss for the charity group? Why?

4. Which payment plan has the highest profit potential assuming that there is very high demand for the boards? Why?

Use Excel to answer. A college admission officer for an MBA program determines that historically candidates have undergraduate grade averages that are normally distributed with standard deviation of .45. A random sample of 25 applications from the current year yields a sample mean grade point average of 2.90.

1. Find a 95% confidence interval for the population mean, μ. (Round the boundaries to 2 decimal places.)

2. Based on the same sample results, a statistician computes a confidence interval for the population mean as 2.81< μ < 2.99. Find the α for this interval and the probability content (1- α) as well. (Round to 4 digits.) (Note: the correct α is a higher number than traditional α used; so don’t worry if your number “looks” wrong!)

Hint: first calculate α/2 using either the lower bound (2.81) or upper bound (2.99); then calculate α. Finally, calculate the probability content of the interval, which is (1- α). And make sure you use the standard error, not the standard deviation, to calculate α/2.

Scenario: Upon successful completion of the MBA program, imagine you work in the analytics department for a consulting company. Your assignment is to analyze one of the following databases:

• Manufacturing
• Hospital
• Consumer Food
• Financial

Select one of the databases based on the information in the Signature Assignment Options.

Provide a 1,600-word detailed, four part, statistical report with the following sections:

• Part 1 - Preliminary Analysis
• Part 2 - Examination of Descriptive Statistics
• Part 3 - Examination of Inferential Statistics
• Part 4 - Conclusion/Recommendations

Part 1 - Preliminary Analysis

Generally, as a statistics consultant, you will be given a problem and data. At times, you may have to gather additional data. For this assignment, assume all the data is already gathered for you.

State the objective:

• What are the questions you are trying to address?

Describe the population in the study clearly and in sufficient detail:

• What is the sample?

Discuss the types of data and variables:

• Are the data quantitative or qualitative?
• What are levels of measurement for the data?

Part 2 - Descriptive Statistics

Examine the given data.

Present the descriptive statistics (mean, median, mode, range, standard deviation, variance, CV, and five-number summary).

Identify any outliers in the data.

Present any graphs or charts you think are appropriate for the data.

Note: Ideally, we want to assess the conditions of normality too. However, for the purpose of this exercise, assume data is drawn from normal populations.

Part 3 - Inferential Statistics

Use the Part 3: Inferential Statistics document.

• Create (formulate) hypotheses
• Run formal hypothesis tests
• Make decisions. Your decisions should be stated in non-technical terms.

Hint: A final conclusion saying "reject the null hypothesis" by itself without explanation is basically worthless to those who hired you. Similarly, stating the conclusion is false or rejected is not sufficient.

Part 4 - Conclusion and Recommendations

Include the following:

• What are your conclusions?
• What do you infer from the statistical analysis?
• State the interpretations in non-technical terms. What information might lead to a different conclusion?
• Are there any variables missing?
• What additional information would be valuable to help draw a more certain conclusion?

A survey of MBA graduates of a business school obtained data on the first-year salary after graduation and years of work experience prior to obtaining their MBA. The data are given in excel.

1. Run the regression analysis (Include all options). Report the least squares regression line. Give the 95% confidence interval for the least squares estimate of the slope. Report the correlation coefficient. Interpret.  Report the coefficient of determination. Interpret. and  Use the ANOVA output and write out the hypothesis being tested, the test statistic, the critical value, p-value, and fully write out the conclusion.

Scenarios 4: A Walexron employee, Lou Scannon, leaked the findings of the safety study to the public and a consumer watchdog group. In a press conference called by Scannon, Lou explanined the safety testing process for the Ranger Helicopter and results in details. Walexron hired Scannon as Director of Purchasing in 2012 and offered him a five year contract. In January 2013, Scannon verbally agreed to a confidentiality provision as an addition to his 5-year written employment contract.

Question: Is the Confidentiality provision within Scannon's employment contract valid?
