One of my recent papers examine important and timely research questions using a field experiment approach in eBay auctions: (i) Can merchandise return policy (MRP; liberalness in the MRP) increase consumers’ willingness to pay? and (ii) is the marginal impact of MRP diminishing? In this study we created three brand new eBay seller profiles, all with zip-codes located within five miles of each other in a college town in the U.S. The eBay stores received exactly the same product description, pictures, outbound shipping policies, etc. The only difference among the three sellers was the extent of liberalness in the MRP and we chose to operationalize MRP liberalness in terms of the time window during which the customer is allowed to return the purchased product. The most conservative MRP (Storefront 1 and 1a) involved a 15-day return window. According to trade publications, this return condition is more conservative than retail-industry averages. Storefront2 and 2a received a 30-day return window, which corresponds closely with retail-industry averages. Finally, Storefront3 and 3a received a 60-day return window, which is more liberal than many retailers offer at this point. The other elements of the return remained constant across the three storefronts. Therefore, in terms of overall return-policy liberalness, it could be argued that Storefront1/1a < Storefront 2/2a < Storefront 3/3a . It is important to note that it is very common in my data that we observe a customer’s bidding behavior in several auctions. [Question] During the revision stage of the journal publication process, one of reviewer’s comment was that the I may use a fixed effects model to control for unobserved individual fixed effects. Do you agree or disagree with the above statement? Please explain with details.

George Garcia, a 23-year-old construction worker, and his wife, Anita, age 20, bring their 4-month-old daughter to the emergency room of a small community hospital. They speak broken English. They have another small child with them, as well as two older women. They are very worried about the infant, who they say has been unable to retain feedings of diluted cow's milk. Now, because of poor sucking and increased sleeping, the infant has not had anything by mouth for the last 24 hours. When asked, the parents say the infant has been sick for 3 or 4 days. The infant is listless, and her eyes are sunken. Anita is newly pregnant with her third child.

The Garcia family lives together in a small house 2 miles from the Mexican border in a predominantly Mexican American neighborhood.. The padrinosor compadres (godparents) live next door to the Garcias. The family is Catholic, and a medal of Our Lady of Guadalupe is on a chain around the older child's neck. The baby has a bracelet with a seed in it around her wrist. The 2 older women with the Garcias are the mothers of George and Anita. George's mother is a curandero, and has been treating the baby with weak specially brewed teas.

1. How would the health care practitioner approach the family to demonstrate respect, compassion, and understanding?

2. Describe family roles and common living arrangements in a family of Mexican-American heritage.

   If the doctor's recommendation is that the infant should be hospitalized, who in the family would make the decision?

3. What is a curandero? Name 2 other kinds of folk practitioners, and describe what they do.

4. Discuss spirituality and the meaning of life for persons of Mexican-American heritage.

5. The infant could have mal de ojo. What is this, and how is it treated? Should the health care professional touch the infant?

You have recently been hired by Swan Motors, Inc. (SMI), in its relatively new treasury management department. SMI was founded 8 years ago by Joe Swan. Joe found a method to manufacture a cheaper battery with much greater energy density than was previously possible, giving a car powered by the battery a range of 700 miles before requiring a charge. The cars manufactured by SMI are midsized and carry a price that allows the company to compete with other mainstream auto manufacturers. The company is privately owned by Joe and his family, and it had sales of $97 million last year.

SMI primarily sells to customers who buy the cars online, although it does have a limited number of company-owned dealerships. Most sales are online. The customer selects any customization and makes a deposit of 20 percent of the purchase price. After the order is taken, the car is made to order, typically within 45 days. SMI’s growth to date has come from its profits. When the company had sufficient capital, it would expand production. Relatively little formal analysis has been used in its capital budgeting process. Joe has just read about capital budgeting techniques and has come to you for help. For starters, the company has never attempted to determine its cost of capital, and Joe would like you to perform the analysis. Because the company is privately owned, it is difficult to determine the cost of equity for the company. Joe wants you to use the pure play approach to estimate the cost of capital for SMI, and he has chosen Tesla Motors as a representative company.

1. You used Tesla as a representative company to estimate the cost of capital for SMI. What are some of the potential problems with this approach in this situation? What improvements might you suggest?

Fueleconomy.gov, the official US government source for fuel economy information, allows users to share gas mileage information on their vehicles. The histogram below shows the distribution of gas mileage in miles per gallon (MPG) from 14 users who drive a 2012 Toyota Prius. The sample mean is 53.3 MPG and the standard deviation is 5.2 MPG. Note that these data are user estimates and since the source data cannot be verified, the accuracy of these estimates are not guaranteed. Report all answers to 4 decimal places. 1. We would like to use these data to evaluate the average gas mileage of all 2012 Prius drivers. Do you think this is reasonable? Why or why not? , because . The EPA claims that a 2012 Prius gets 50 MPG (city and highway mileage combined). Do these data provide strong evidence against this estimate for drivers who participate on fueleconomy.gov? Conduct a hypothesis test. Round numeric answers to 3 decimal places where necessary. 2. What are the correct hypotheses for conducting a hypothesis test to determine if these data provide strong evidence against this estimate for drivers who participate on fueleconomy.gov? (Reminder: check conditions) A. H0:μ=50 vs. HA:μ>50.3 B. H0:μ=50 vs. HA:μ≠50 C. H0:μ=50.3 vs. HA:μ<50 D. H0:μ=53.3 vs. HA:μ≠53.3 3. Calculate the test statistic. 4. Calculate the p-value. 5. How much evidence do we have that the null model is not compatible with our observed results? A. little evidence B. very strong evidence C. strong evidence D. extremely strong evidence E. some evidence 6. Calculate a 95% confidence interval for the average gas mileage of a 2012 Prius by drivers who participate on fueleconomy.gov.

To illustrate the effects of driving under the influence​ (DUI) of​ alcohol, a police officer brought a DUI simulator to a local high school. Student reaction time in an emergency was measured with unimpaired vision and also while wearing a pair of special goggles to simulate the effects of alcohol on vision. For a random sample of nine​ teenagers, the time​ (in seconds) required to bring the vehicle to a stop from a speed of 60 miles per hour was recorded. Complete parts​ (a) and​ (b).

​Note: A normal probability plot and boxplot of the data indicate that the differences are approximately normally distributed with no outliers.

TABLE IS BELOW.

​(a) Whether the student had unimpaired vision or wore goggles first was randomly selected. Why is this a good idea in designing the​ experiment?

A.

This is a good idea in designing the experiment because it controls for any​ "learning" that may occur in using the simulator.

B.

This is a good idea in designing the experiment because the sample size is not large enough.

C.

This is a good idea in designing the experiment because reaction times are different.

​(b) Use a​ 95% confidence interval to test if there is a difference in braking time with impaired vision and normal vision where the differences are computed as​ "impaired minus​ normal."

The lower bound is

?

The upper bound is

?

​(Round to the nearest thousandth as​ needed.)

State the appropriate conclusion. Choose the correct answer below.

There is sufficient evidence to conclude there is a difference in braking time with impaired vision and normal vision.

There is insufficient evidence to conclude there is a difference in braking time with impaired vision and normal vision.

Sixteen-year-old Michelle Portman was out driving at night near Sandusky, Ohio with her friend Katie Webster in the front passenger seat. They came to a railroad crossing with multiple tracks, where the mechanical arm had descended and warning bells were sounding. A Conrail train had suffered mechanical problems and was stopped 200 hundred feet from the crossing, where it had been stalled for close to an hour. Michelle and Katie saw several cars ahead of them go around the barrier and cross the tracks, despite the fact that Ohio’s vehicle and traffic laws prohibited this practice. Michelle had to decide whether she would do the same.
Long before Michelle made her decision, the train’s engineer (a Conrail employee) had seen the heavy Saturday night traffic crossing the tracks and realized the danger. The conductor and brakeman also understood the peril, but rather than posting a flagman who could have stopped traffic when a train approached, they walked to the far end of their train to repair the mechanical problem. A police officer had come upon the scene, told his dispatcher to notify the train’s parent company Conrail of the situation, and left.
Michelle made the decision to cross the tracks. She slowly followed the cars ahead of her. Seconds later, both girls were dead. A freight train traveling 60 miles per hour struck the vehicle broadside, killing Michelle and Katie instantly.
Michelle’s mother sued Conrail for negligence. The company argued that it was Michelle’s decision, one that violated Ohio traffic laws, which led to her death. Ohio is a comparative negligence state. Discuss both the plaintiff’s claim and Conrail’s defense. What verdict will result?
