Exercise 3.13 —*** Challenging Question ✶✶✶.
Two women, Anna and Bess, claim to be the legal owners of a diamond ring that -
each claims - has great sentimental value. Neither of them can produce evidence of
ownership and nobody else is staking a claim on the ring. Judge Sabio wants the ring to
go to the legal owner, but he does not know which of the two women is in fact the legal
owner. He decides to proceed as follows. First he announces a fine of $F > 0 and then
asks Anna and Bess to play the following game.
Move 1: Anna moves first. Either she gives up her claim to the ring (in which case
Bess gets the ring, the game ends and nobody pays the fine) or she asserts her claim, in
which case the game proceeds to Move 2.
Move 2: Bess either accepts Anna's claim (in which case Anna gets the ring, the game
ends and nobody pays the fine) or challenges her claim. In the latter case, Bess must
put in a bid, call it B, and Anna must pay the fine of $F to Sabio. The game goes on to
Move 3.

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.
Researchers conducted a prospective cohort study to assess the association between dietary supplements and cognitive ability among children. A total of 500 children age 12-17 years who take an omega-3 fatty acid supplement are compared with 500 children age 12-17 years who do not take an omega-3 fatty acid supplement. Researchers follow the children for 2 years. During this time, 300 children who take the supplement earn what is classified as a “high” score on a cognitive test while 200 children who do not take the supplement earn what is classified as a “high” score on the same cognitive test. Show calculations.

- A group of health professionals produced a cholesterol drug. To measure the effectiveness of this drug they implemented a program that offered free drugs to people to decrease their cholesterol level. Health professionals also collected a sample of people, who did not have the drug, to act as a control group. Health professionals then measured cholesterol level of all individuals in year 1, before any cholesterol drug were given out, and then measured the same group of individuals again in year 2 after the cholesterol drugs had been administered. Consider the following model to evaluate the effectiveness of the drug on people's cholesterol level: cholie = Bo + 8od2, + B1drugit + Vịt chol= cholestrol of individual i, in year t d2;= binary variable equal to 1 if the time period is year 2, and 0 otherwise drug= binary variable equal to 1 if individual i took the drug in year t, and 0 otherwise V= composite error consisting of the unobserved, time-constant effect (a;) and the idiosyncratic…arrow_forwardMany parents allow underage children to drink alcohol in limited situations when an adult is present to supervise.

(1982) report on a drug designed to reduce hypertension (high blood pressure). Such hypotensive drugs are frequently effective but are also linked to side effects like irritability and a decline in energy. Seventy-five patients with mild hypertension were put on hypotensive drugs and their progress was monitored by doctors and spouses. When asked to rate the treated patients as improved, worse, or unchanged, the doctors rated all 75 patients as "improved." Meanwhile, the spouses rated 74 of the 75 patients as "worse." Why might spouses and doctors differ in their opinion about the effect of going on blood pressure medication?arrow_forward
- Textbook authors must be careful that the reading level of their book is appropriate for the target audience. Some methods of assessing reading level require estimating the average word length. We've randomly chosen 20 words from a randomly selected page in Intro Stats and counted the number of letters in each word: 5, 5, 2, 11, 3, 5, 6, 8, 5, 4, 7, 2, 9, 4, 8, 10, 4, 7, 6, 9 Suppose that our editor was hoping that the book would have a mean word length of 6.8 letters. Does this sample indicate that the authors failed to meet this goal? With a significance level of 0.05, test an appropriate hypothesis and state your conclusion. (i.e state the appropriate null and alternative hypotheses, calculate the test statistic, conclude and interpret it).arrow_forwardA study was done in 1998 by Dr. Benjamin Levine to explore the role of altitude training in athletic performance. First, he trained athletes at low altitude, then measured their finish times in a 5 kilometer run. Then the athletes were placed into one of the following groups: I, living and training at high altitude; Il, living at high altitude and training at low; or Ill, living and training at low altitude. The athletes were then retested in another low-altitude 5 K race. In this study, what are the control and experimental data? What are the dependent and independent variables?

Researchers questioned 1000 individuals fromCalifornia between the ages of 20 and 85 about their eating habits, andmeasured their weight and height. On average, participants ate chocolatetwice a week and had a body mass index (BMI) of 28. There was anobserved difference of five to seven pounds in weight between those whoate chocolate five times a week and those who did not eat any chocolate atall, with the chocolate eaters weighing less on average.

In order to assess the damages for the various units, the owners' association sent out a letter to owners and asked if people were willing to make their units available for destructive testing. Destructive testing was conducted in some of these units as a result of the responses. Based on the tests, the owners' association inferred the damage over the entire condo complex. Do you think that the inference is valid in this case? a). No, the inference is not valid. It is an example of sample selection bias because owners whose units were relatively more damaged were more likely to make theor units available for destructive testing. b). No, the inference is not valid because not all units were tested. c). Yes, the inference is valid.
