9. You are interested in studying the average duration of time (in minutes) it takes Temple University students to drive to campus. The conventional wisdom is that on average it takes students 30 minutes to drive to campus. To examine this, you randomly sample n=15 students and record this information. From the sample, you compute a sample mean of 26 with a sample standard deviation of 6. Conduct a two-tailed hypothesis test with 95% confidence. Then, construct a 95% confidence interval to confirm your answer.

Best Buy ranks number 72 on the Fortune 500; it is the largest consumer electronics retailer in the world. Best known for its discounted high-quality products, customer centered approach, sustainable outreach, and extensive recycling program. Best Buy is listed as a “socially responsible” company. It was founded by Richard Schulze in 1966. Since then the company has undergone many changes.

College students, who wanted higher-end electronics, were the first customers they targeted. In 2000, when sales growth slowed, Best Buy acquired Geek Squad, a repair service. This acquisition led to their Concept 5 stores, where products are sold, and customers taught how to use them. This improved service turnaround time and increased customer satisfaction. By 2009, the company became the primary online and brick-and-mortar provider of consumer electronics.

             Best Buy views itself as a customer-centered organization. The company uses www.BestBuy.com to learn more about its customer needs and preferences. Customers can use that website to rate every product purchased. In 2007, the Company published its first Corporate Social Responsibility Report (SR) as result of the customers concern for sustainability. Electronic waste was filling landfills, and their customers wanted to see this problem addressed. In response to their concerns, Best Buy implemented a wide-scale electronics recycling program.   In 2009 Best Buy set a goal to reduce carbon emissions by 45%; by the end of 2016 they had reached nearly 47%.

             Today Best Buy employs a Chief Ethics Office and maintains a blog for company employees; it covers ethical lapses and related issues. Employees can visit the website and read about the company policy regarding ethically questionable behaviors and learn tips on how to best defend themselves from crossing ethical boundaries. Hubert Joly was appointed CEO in 2012 after a scandal forced out CEO, Brian Dunn and Chairman, Richard Schulz.

Under Joly, Best Buy, once again, became a growth company. He implemented its “Renew Blue” strategy, adding new product lines and services and emphasizing both in-store and online customer opportunities. Its Geek Squad division began an in-store, online, and home advisory program. He expanded into both Canadian and Mexican markets. Operations in China and Europe were closed to reduce costs, and he closed some domestic stores, under his lean management mandate.

             To improve customer service, the “Geek Squad hours were expanded to provide 24-hour service on site, at home, or through the Internet. The tech experts make about 4 million home calls a year. Walmart and Amazon their biggest competitors do not offer comparable at-home services. In March 2017, “Renew Blue” was officially closed by Joly and pronounced a success.

             In 2017, Joly announced the company will implement “Best Buy 2020 - Building the New Blue.” Best Buy began a try-before-you-buy program which allows the customer to rent gadgets such as audio equipment, fitness trackers, smartwatches, and cameras. If the customer decides to keep the product, 20% of the rental fee is deducted and applied to the final cost of the product.

             Best Buy will continue demonstrating new technology solutions, contracts and services and sustainability . The company plans to enhance their smart home areas in all stores, roll out its Best Buy Smart Home Powered by Vivint home automation and security offering to 450 stores, which will add 1,500 dedicated smart home employees. The “Geek Squad” expanded services will include “Smart Home ‘Total Tech Services, which will service every electronic product in your home no matter where the product was purchased and create a totally integrated technology system for your home.

Another service Best Buy will provide is the Smart Home Senior Care Services,” which is considered an “untapped white space opportunity.” The electronic “Assured Living” system will allow millennials /caregivers to look in on their aging parents while permitting the seniors to live independently. Mr. Joly envisions rolling out a broader business of sensor-based senior services, sold through health-and-wellness departments in Best Buy’s more than 1,000 stores.   With an aging population in the U.S., there will be 70 million people who will be seniors in 2027. Best Buy sees this growth opportunity and will use the Smart Home Business and its ability to get into people’s home as a trusted adviser.

Review the discussion question and answer below. Do you agree with the answer? why or why not? Give your opinion.

Discussion Question:

1. Suppose an employer gives employees an insurance discount based on number of hours of physical fitness activities. Who benefits from the program? Who is harmed? Is this ethical?

2. Suppose an employer charges all employees the same premium, regardless of their health habits, Who benefits? Who is harmed? Is this ethical?

Answer:

1) In such a scenario, all the concerned parties, i.e the employer , insurance company and the employees will benefit from the program. When the employee is encouraged to participate in physical activities, it would help in improving the health and wellness of the employee. Also, the employee would receive discounts on their insurance program. The improvement in health will lead to an increase in the productivity of the employee and make him more efficient at the workplace. This could be due to the fact that a healthy body leads to a healthy mind, which in turn will lead to fewer episodes of absenteeism from workplace on account of ill health.

These benefits due to a better health benefit both the employee and the employer. Also, the insurance company will be benefit as they would have lesser insurance claims to settle on account of ill health.

However, if the organization imposes extreme methods to encourage physical fitness or expects the employees to follow rigorous physical activities in order to claim the discounts then it could prove to be detrimental to both the employer and the employee. It is a known fact that people tend to dislike imposition of extreme forms of physical activities. Under such a scenario, employees would feel burdened with the program and will lose enthusiasm towards the workplace. The employer will also be at loss. Employer could lose talented employees and also the organization will have to incur monetary losses in case the program fails.

The program can be ethical if the limits and the conditions to qualify for discounts, the kind of physical activity expected, the amount of physical activity expected etc is discussed and implemented after consultation with the employees. If the physical fitness activities are left to the discretion of the employees without much interference from the organization, then it may be ethical.

However, if the organization is the sole planner of the entire program and imposes difficult and strenuous physical activities to be completed or threatens the employees with fines or other punishments for refusing to participate in the program then it can be unethical and harmful to both the employer and the employee.

2)  When an employer charges same premium regardless of health habits it is beneficial to the employer and employee. It provides full premium to the employee and any sudden health problems can also be covered as health will not be the same always. This also makes everyone in the company equal and gives equal rights and benefits to everyone which is also ethical.

Each of the variables are described as follows.

Feelings towards Barack Obama are measured 0-100 with higher values indicating more positive opinions.

Gender is variable that equals 1 for respondents who identify as female and 0 for respondents who do not.

Race is a variable that equals 1 for respondents who identify as white and 0 for respondents who do not.

Age is the number of years the respondent reports having been alive.

Income is a 28-point scale with higher values denoting greater income earned.
