Textbook Question
Chapter 1, Problem 1.34ACI
Can money spent on gifts buy love? Is the gift you purchased for that special someone really appreciated? This was the question of interest to business professors at Stanford University. Their research was published in the Journal of Experimental Social Psychology (Vol. 45, 2009). In one study, the researchers investigated the link between engagement ring price (dollars) and level of appreciation of the recipient (measured on a 7-point scale where 1 = “not at all” and 7 = “to a great extent”). Participants for the study were those who used a popular Web site for engaged couples. The Web site's directory was searched for those with “average” American names (e.g., “John Smith,” “Sara Jones”). These individuals were then invited to participate in an online survey in exchange for a $10 gift certificate. Of the respondents, those who paid really high or really low prices for the ring were excluded, leaving a
- a. Identify the experimental units for this study.
- b. What are the variables of interest? Are they quantitative or qualitative in nature?
- c. Describe the population of interest.
- d. Do you believe the sample of 33 respondents is representative of the population? Explain.
- e. In a second designed study, the researchers investigated whether the link between gift price and level of appreciation is stronger for birthday gift-givers than for birthday gift-receivers. The participants were randomly assigned to play the role of gift-giver or gift-receiver. Assume that the sample consists of 50 individuals. Use a random number generator to randomly assign 25 individuals to play the gift-receiver role and 25 to play the gift-giver role.

. What the heck is this GDP thingy?
It is Thursday afternoon, just a few days before the holiday season starts in your region, and you decided to visit your uncle Chao who owns a local delivery company. While sitting in the living room watching the evening news with your uncle, you heard the news reporter stating the following with an optimistic tone: "According to recent studies, gross domestic product (GDP) is rising due to an increase in consumer spending. The increase in spending was due to an increase in consumer confidence because the job market has shown a positive increase in both employment and income."
Immediately, your uncle Chao looked at you with some confusion on his face and asked:
What the heck is GDP, and why does the news dude seem excited about its increase?
Does this “good” change in this GDP thingy have any effect on my delivery business? How?
Do I need to do something different to prepare for the rise in GDP? How?
3. I need people who don’t want me!
As an operations manager at a factory that produces manual tools, you were tasked with preparing a new site for expansion. The plan is to start production in the new location within 6 months from the current date. The new location requires 100 workers to operate fully. The workers you need don’t require any form of education or special skills because the tasks at the factory are simple and straightforward. In other words, you typically hire lower-skilled workers. In recent years, your company has been having problems finding workers who meet those criteria because the demand for them is so high. While sitting in your office, your teammate, Alejandra, walked to your office and said, "Have you heard the recent news about the economy? They said that investment has declined, and government spending has declined too. They also said that GDP is expected to shrink in the next 6 to 10 months. I wonder what is next."
Then, she looked at you and said:

- Before the Civil War, the South traded with the North and with England. The South sold cotton and bought manufactured goods and food. During the war, one of President Lincoln's first actions was a blockade of the ports in the South to prevent this trade. The South had to increase its production of munitions and food. Draw a point to show the South's production point prior to the Civil War. Label it 1. Draw a point to show the South's consumption point prior to the Civil War. Label it 2.

For the downstream mill, the marginal profitability of producing boxes declines with volume. For example, the first unit of boxes increases earnings by $10, the second by $9, the third by $8, and so on, until the tenth unit increases profit by just $1. The cost the upstream mill incurs for producing enough paper (one "unit" of paper) to make one unit of boxes is $3.50. Assume the two mills operate as separate profit centers, and the paper mill sets the price of paper. It follows that the marginal profitability of boxes represents the highest price that the box division would be willing to pay the paper division for boxes.. Furthermore, assume that fixed costs are $0 for the paper mill. The following table summarizes the quantity, total revenue, and marginal costs from the perspective of the paper mill for selling paper to the box mill at various prices. In the following table, fill in the marginal revenue, total cost, and total…arrow_forwardPlanes frequently push back from the gate on time, but then wait 2 feet away from the gate until it is time to queue up for takeoff. This increases fuel consumption and increases the time that passengers must sit in a cramped plane awaiting takeoff. The following table shows the pay schedule for the flight crew. Pay Per diem Holding pay per hour Flight Attendant Captain First Officer $3 $3 $3 $20 $20 $20 Hourly wage (after push back) $38 $184 $50 Per diem pay indicates how much the flight crew earns once it checks into the airport. Holding pay indicates how much the flight crew earns after it loads the plane. Hourly wage indicates how much the flight crew earns after it pushes back from the gate and turns on the beacon. In this scenario, who does not have an incentive to push back from the gate as early as possible? Check all that apply.
