Shopping vehicle and judgment. Refer to the Journal of Marketing Research (December 2011) study of grocery store shoppers’ judgments, Exercise 2.85 (p. 88). For one part of the study, 11 consumers were told to put their arm in a flex position (similar to carrying a shopping basket) and then each consumer was offered several choices between a vice product and a virtue product (e.g., a movie ticket vs. a shopping coupon, pay later with a larger amount vs. pay now).
Based on these choices, a vice choice score was determined on a scale of 0 to 100 (where higher scores indicate a greater preference for vice options). The data in the next table are (simulated) choice scores for the 11 consumers.
Suppose that the average choice score for consumers with an extended arm position (similar to pushing a shopping cart) is known to be μ. = 50.. The researchers theorize that the mean choice score for consumers shopping with a flexed arm will be higher than 43 (reflecting their higher propensity to select a vice product) Test the theory at α = .05.

- Based on a survey of 12,344 U.S. college students and 6,729 Canadian college students, Kuo, Adlaf, Lee, Gliksman, Demers, and Wechsler (2002) report that alcohol use is more common among Canadian than U.S. students, but heavy drinking (five or more drinks in a row for males, four or more for females) is significantly higher among U.S. students than Canadian students. Is this an example of a survey research design?arrow_forwardA report summarizes a survey of people in two independent random samples. One sample consisted of 700 young adults (aged 19 to 35) and the other sample consisted of 200 parents of children aged 19 to 35. The young adults were presented with a variety of situations (such as getting married or buying a house) and were asked if they thought that their parents were likely to provide financial support in that situation. The parents of young adults were presented with the same situations and asked if they would be likely to provide financial support to their child in that situation. 1. When asked about getting married, 41% of the young adults said they thought parents would provide financial support and 43% of the parents said they would provide support. Carry out a hypothesis test to determine if there is convincing evidence that the proportion of young adults who think parents would provide financial support and the proportion of parents who say they would provide support are different.…arrow_forwardA report summarizes a survey of people in two independent random samples.

The parents of young adults were presented with the same situations and asked if they would be likely to provide financial support to their child in that situation. 1. The report stated that the proportion of young adults who thought parents would help with buying a house or apartment was 0.37. For the sample of parents, the proportion who said they would help with buying a house or an apartment was 0.27. Based on these data, can you conclude that the proportion of parents who say they would help with buying a house or an apartment is significantly less than the proportion…arrow_forward
- In the Salsberry (2003) study shared in this weeks module, the researcher presents the following results of the statistical analysis: "With respect to family configuration, 20% of the children enrolled in Medicaid, 29% of the uninsured children, and 44% of the privately insured children were in families where the adults were in a “partnered relationship”, [χ2 (2,N = 392) = 21.95; P = .0001]" What type of analysis does this statement reflect?arrow_forwardIn a study of whether taking a garlic supplement reduces the risk of getting a cold, participants were assigned to either a garlic supplement group or to a group that did not take a garlic supplement.† Based on the study, it was concluded that the proportion of people taking a garlic supplement who get a cold is lower than the proportion of those not taking a garlic supplement who get a cold. Do you think that the study was conducted in a reasonable way? What additional information would you want in order to evaluate this study? (Select all that apply.) A) whether the patients knew which treatment they were receiving B) whether the patients were randomly assigned to the treatments C) whether the patient's last name started with A through M D) whether the patient's cold lasted more than a week E) whether the experiment was conducted on a sufficient number of patients so that the differences observed could not be attributed to chancearrow_forwardAronson and Mills (1959) conducted an experiment to see whether people's liking for a group is influenced by the severity of initiation. They reasoned that when people willingly undergo a severe initiation to become members of a group, they are motivated to think that the group membership must be worthwhile. Otherwise, they would experience cognitive dissonance: Why put up with severe initiation for the sake of a group membership that is worthless? In their experiment, participants were randomly assigned to one of three treatment groups: Group 1 (control) had no initiation. Group 2 (mild) had a mildly embarrassing initiation (reading words related to sex out loud). Group 3 (severe) had a severely embarrassing initiation (reading sexually explicit words and obscene words out loud). After the initiation, each person listened to a standard tape-recorded discussion among the group that they would now supposedly be invited to join; this was made up made to be as dull and banal as possible.…arrow_forward
- The health board of a major city wants to know if people who have different types of healthcare coverage (HMO, Medicare/Medicaid, or no insurance) go to different types of hospitals (privately-funded, government-funded, or free clinic) when they are injured.

Quality of product was the number one influence, with 96% of consumers stating that quality influences their buying decisions. How a company handles complaints was number two, with 85% of consumers reporting it as an influence in their buying decisions. Suppose a random sample of 1,100 consumers is taken and each is asked which of these three factors influence their buying decisions.
