xt:Bong-Cha is deciding what to do during the 30-minute break between her college classes. One rule she could follow is, "Choose the activity with the highest value" (A). Another rule she could follow is, "Choose the activity with the lowest opportunity cost" (B). Do you think Bong-Cha's choice if she follows rule (A) will be the same as the choice she would make if she followed rule (B)? [another way to think about it, "Is rule (A) identical to rule (B) in a sense that they would both induce the same choice?"].
According to Wine-Searcher, wine critics generally use a wine-scoring scale to communicate their opinions on the relative quality of wines. Wine scores range
from 0 to 100, with a score of 95 – 100 indicating a great wine, 90 – 94 indicating an outstanding wine, 85 – 89 indicating a very good wine, 80 – 84
indicating a good wine, 75 - 79 indicating a mediocre wine, and below 75 indicating that the wine is not recommended. Random ratings of a pinot noir recently
produced by a newly established vineyard in 2018 follow:

a. Develop a point estimate of mean wine score for this pinot noir (to 2 decimals).
b. Develop a point estimate of the standard deviation for wine scores received by this pinot noir (to 4 decimals).
Why can we not use first differences when we have independent cross sections in two years (as opposed to panel data)?

- A researcher investigated whether a father's level of optimism was predictive of his son's optimism as a young adult. Twenty (20) fathers and sons who agreed to participate in the study were administered a scale measuring their current level of optimism (the scale ranged from 10 to 50), with higher scores indicating greater optimism.arrow_forwardThe Watch Corporation of Switzerland claims that its watches on average will neither gain nor lose time during a week.

In this experiment, you have collected data from four major cities, namely Birmingham, Manchester, Bristol and Glasgow. What method is suitable for studying this project? Give an explanation.arrow_forwardNumber of Scenario Firms Type of Product Market Model A large city has lots of small shops where people can buy sweaters. Each store's sweaters reflect the style of that particular store. Additionally, some stores use higher-quality yarn than others, which is reflected in their price. Dozens of companies produce plain white socks. Consumers regard plain white socks as identical and don't care about who sells them their socks. The technology for producing socks is widely known, and any reputable person who wanted to start a sock manufacturing business could obtain a loan from a bank to buy the necessary machinery. In a large city, two taxi companies own all the licenses that the city will grant to operate taxis. Consumers don't care which cab company they take-if they decide it's worth taking a cab, they flag down the nearest one.

As a result, the news has been covering this health issue, with many headlines involving famous NFL players. It has been assumed that this has made most Americans that follow football more aware of the risks involved in playing the game. However, we have not seen a decline in the number of young boys, ages 8-10, that are joining football leagues. For this age group to take part in playing football, these young boys need to have the permission of a parent or guardian to play, which demonstrates the adults support to their participation. Given the risks to these young boy’s health, we wonder why would parents allow or even encourage their children to play football? Using what you know about qualitative research, briefly explain (one page): How would you design a qualitative research study, with the goal of gaining an understanding of why parents allow their…arrow_forward
- Researchers conducted an observational study of automobile drivers and their cell phone use by manually observing traffic in heavily congested areas. They would record the amount of time they observed individual drivers on the phone while operating their vehicle in stop and go traffic and the number of accidents on a particular section of highway over the course of a month. The accompanying graph depict the data they recorded, each point represents a 1 mile section of heavily congested roads. From the data, which of these is a potentially valid conclusion? Cell-phone use while driving increases the rate of accidents. O Car accidents and cell-phone use have no relationship. The increasing rate of car accidents causes increased phone-call length. A conclusion cannot be made; the data ignores the omitted variable of which cell-phone provider each person uses. If the x and y variables were swapped, what would the new slope be? zero positive Number of car accidents 10- 9- 8- 7- 5- 4- 3- 2-…arrow_forwardA merchant who sells newspapers and magazines at the corner kiosk heard you manage the Times’ inventory and asks for your advice.

She pays $0.50 for each newspaper and sells them for $1.50 each. She has kept detailed records of her past sales of the Chicago Sun Times and estimates that 10% of the time she sells 10 newspapers, 40% of the time she sells 11, 30% of the time she sells 12, and 20% of the time she sells 13.
