Reba Dixon is a fifth-grade school teacher who earned a salary of $38,000 in 2020. She is 45 years old and has been divorced for four years. She receives $1,200 of alimony payments each month from her former husband (divorced in 2016). Reba also rents out a small apartment building. This year Reba received $50,000 of rental payments from tenants and she incurred $19,500 of expenses associated with the rental.

Reba and her daughter Heather (20 years old at the end of the year) moved to Georgia in January of this year. Reba provides more than one-half of Heather’s support. They had been living in Colorado for the past 15 years, but ever since her divorce, Reba has been wanting to move back to Georgia to be closer to her family. Luckily, last December, a teaching position opened up and Reba and Heather decided to make the move. Reba paid a moving company $2,250 to move their personal belongings, and she and Heather spent two days driving the 1,600 miles to Georgia.

Reba rented a home in Georgia. Heather decided to continue living at home with her mom, but she started attending school full time in January and throughout the rest of the year at a nearby university. She was awarded a $3,360 partial tuition scholarship this year, and Reba helped out by paying the remaining $500 tuition cost. If possible, Reba thought it would be best to claim the education credit for these expenses.

Reba wasn't sure if she would have enough items to help her benefit from itemizing on her tax return. However, she kept track of several expenses this year that she thought might qualify if she was able to itemize. Reba paid $6,520 in state income taxes and $14,100 in charitable contributions during the year. She also paid the following medical-related expenses for herself and Heather:

Shortly after the move, Reba got distracted while driving and she ran into a street sign. The accident caused $1,020 in damage to the car and gave her whiplash. Because the repairs were less than her insurance deductible, she paid the entire cost of the repairs. Reba wasn’t able to work for two months after the accident. Fortunately, she received $2,000 from her disability insurance. Her employer, the Central Georgia School District, paid 60 percent of the premiums on the policy as a nontaxable fringe benefit and Reba paid the remaining 40 percent portion.

A few years ago, Reba acquired several investments with her portion of the divorce settlement. This year she reported the following income from her investments: $2,200 of interest income from corporate bonds and $1,740 interest income from City of Denver municipal bonds. Overall, Reba’s stock portfolio appreciated by $13,510, but she did not sell any of her stocks.

Heather reported $6,400 of interest income from corporate bonds she received as gifts from her father over the last several years. This was Heather’s only source of income for the year.

Reba had $11,270 of federal income taxes withheld by her employer. Heather made $1,120 of estimated tax payments during the year. Reba did not make any estimated payments. Reba had qualifying insurance for purposes of the Affordable Care Act (ACA).

a. Determine Reba’s federal income taxes due or taxes payable for the current year. Use Tax Rate Schedule for reference. (Do not round intermediate values. Leave no answer blank. Enter zero if applicable.)

The term “Marketing Myopia” was coined by the late Harvard Business School marketing professor, Theodore Levitt, in a 1960 HBR article (republished in 2004). The “heart of the article,” according to Deighton, a distinguished Harvard Professor, is Levitt’s argument that companies are too focused on producing goods or services and don’t spend enough time understanding what customers want or need. Therefore, he “encouraged executives to switch from a production orientation to a consumer orientation.” As Levitt used to tell his students, “People don’t want a quarter-inch drill. They want a quarter-inch hole!”

“The genius of the original article is that it is so easy to be myopic when it comes to marketing,” says Deighton. “Any marketer is obligated to be concerned with programs, tactics, campaigns, etc. Unfortunately, the clock never stops long enough to answer the question, ‘Why are you doing what you are doing?’ So it’s far too easy to lose sight of the big picture.” The other thing that made the article so significant at the time of its publication is that it reminded CEOs that marketing is part of their job: “[Levitt] tells the leader of the organization: you are in business because you have a customer. Therefore you have to think about marketing,” Deighton explains.

In 2010, Craig Smith at INSEAD, Minette Drumwright at UT Austin, and Mary Gentile at Babson, published a paper criticizing Marketing Myopia. They posited that marketers have taken Levitt’s advice to an extreme, creating a new kind of short sightedness, marked by a single-minded focus on the customer, a narrow definition of the customer, and a failure to address the multiple stakeholders who have arisen out of the “changed societal context of business”. There is no doubt that Levitt believed the entire corporation must be viewed as a customer-creating and customer-satisfying organism, and Deighton admits that this is one of the potential pitfalls of Levitt’s original idea: it “puts great trust in the consumer.” In his original article, Levitt acknowledged how difficult it can be to listen to customers; he wrote: “Consumers are unpredictable, varied, fickle, stupid, shortsighted, stubborn, and generally bothersome.” But Smith, Drumwright, and Gentile go even further, arguing that it’s not just about listening to consumers but about hearing all of the stakeholders who contribute to your company’s success.

1. Do you agree or disagree with Smith, Drumwright and Gentile’s assessment of the concept of Marketing Myopia? Why or why not? What stakeholder(s) might be important to listen to in formulating a new take on marketing Myopia and why?

We reject the claim that retaking the SAT increases the score on average by more than 25 points.

We have proven that retaking the SAT increases the score on average by more than 25 points.

How do California high school students compare to students nationwide in their college readiness, as measured by their SAT scores? The national average scores for the class of 2017 were 533 on Evidence-Based Reading and Writing and 527 on the math portion.† Suppose that 100 California students from the class of 2017 were randomly selected and their SAT scores were recorded in the following table.

(a)

Do the data provide sufficient evidence to indicate that the average Evidence-Based Reading and Writing score for all California students in the class of 2017 differs from the national average? Use α = 0.05.

State the null and alternative hypotheses.

H₀: μ < 527 versus H_a: μ > 527

H₀: μ = 533 versus H_a: μ > 533     

H₀: μ = 533 versus H_a: μ ≠ 533

H₀: μ = 533 versus H_a: μ < 533

H₀: μ ≠ 527 versus H_a: μ = 527

Find the test statistic and the p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.)

z=

p-value =

State your conclusion.

The p-value is less than alpha, so H₀ is rejected. There is sufficient evidence to indicate that the average Evidence-Based Reading and Writing score for all California students in the class of 2017 is different from the national average.

The p-value is greater than alpha, so H₀ is not rejected. There is sufficient evidence to indicate that the average Evidence-Based Reading and Writing score for all California students in the class of 2017 is different from the national average.    

The p-value is greater than alpha, so H₀ is not rejected. There is insufficient evidence to indicate that the average Evidence-Based Reading and Writing score for all California students in the class of 2017 is different from the national average.

The p-value is less than alpha, so H₀ is rejected. There is insufficient evidence to indicate that the average Evidence-Based Reading and Writing score for all California students in the class of 2017 is different from the national average.

(b)

Do the data provide sufficient evidence to indicate that the average math score for all California students in the class of 2017 is different from the national average? Use α = 0.05.

State the null and alternative hypotheses.

H₀: μ < 527 versus H_a: μ > 527

H₀: μ = 533 versus H_a: μ > 533   

  H₀: μ ≠ 527 versus H_a: μ = 527

H₀: μ = 533 versus H_a: μ < 533

H₀: μ = 527 versus H_a: μ ≠ 527

Find the test statistic and the p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.)
