Chapter 1, Problem 28PS
The results of a 2013 Adobe system study on retail apps and buying habits reveal insights on perceptions and attitudes towards mobile shopping using retail apps and browsers, providing new direction for retailers to develop their digital published strategies (adobe.ly/11gt8Rq). Increased consumer interest in using shopping application means retailers must adapt to meet rising expectation for specialized mobile shopping experiences. The results indicate that tablet user (55%) are almost twice as likely as smartphone users (28%) to use their device to purchase and services. The findings also reveal that retails and catalog apps are rapidly catching up to mobile browsers as a viable shopping channel: nearly half of all mobile shoppers are interested in using apps instead of a mobile browser (45% of tablet shoppers and 49% of smartphone shoppers). The research is based on an online survey with a sample of 1,003 consumers. Identify potential concerns with coverage, nonresponse, sampling, and measurement errors.

A research article on the effect of multitasking on grade performance describes an experiment in which 62 undergraduate business students were randomly assigned to one of two experimental groups. Students in one group were asked to listen to a lecture but were told that they were permitted to use cell phones to send text messages during the lecture. Students in the second group listened to the same lecture but were not permitted to send text messages. Afterwards, students in both groups took a quiz on material covered in the lecture. Data from this experiment are summarized in the accompanying table.
For 25 years, Arthur Reynolds and Judy Temple tracked more than 1,400 children who participated in a publicly funded early childhood development program beginning at age 3. They found that children who participated in the program showed higher levels of educational attainment, socioeconomic status, and job skills, as well as lower rates of substance abuse, felony arrest, and incarceration, than those who did not receive school-based early education. One possible theory for the success of this program is that improving school readiness improved the children's success in school. The improved success in school in turn improved their readiness for adulthood, resulting in increased job skills and socioeconomic status as well as lower rates of substance abuse.

- Suzanne Zeedyk, a developmental psychologist at Dundee University’s School of Psychology, conducted a pilot study in which parents started a half-hour walk with their infants in a parent-facing or an away-facing stroller and then switched to the other type of stroller midway. Her results suggest that parents talked less to the babies, the babies had higher heart rates, and they were less likely to fall asleep in away-facing strollers than in parent-facing strollers. You are interested in testing the hypothesis that babies who travel in parent-facing strollers have different expressive vocabularies than babies who travel in away-facing strollers. You randomly assign 13 newborns to parent-facing strollers and 13 newborns to away-facing strollers. You then test the babies’ expressive vocabularies at age 36 months using the Expressive Vocabulary Test (EVT), which is designed primarily to assess children’s expressive vocabulary.

- In studies examining the effect of humor on interpersonal attractions, McGee and Shevlin (2009) found that an individual’s sense of humor had a significant effect on how the individual was perceived by others. In one part of the study, female college students were given brief descriptions of a potential romantic partner. The fictitious male was described positively as being single and ambitious and having good job prospects. For one group of participants, the description also said that he had a great sense of humor. For another group, it said that he has no sense of humor. After reading the description, each participant was asked to rate the attractiveness of the man on a seven-point scale from 1 (very unattractive) to 7 (very attractive). A score of 4 indicates a neutral rating. The females who read the “great sense of humor” description gave the potential partner an average attractiveness score of M = 4.53 with a standard deviation of s = 1.04.

A random sample of students receiving free-and-reduced lunch at five different Connecticut elementary schools were offered a choice between 2 lunch options. One was a typical school lunch prepared off and warmed on campus, while the other was a healthier school lunch made on campus from a variety of fruits, vegetables, and lean protein. For each child, researchers kept track of whether or not the child selected the healthier option. The research question was whether of not the healthier option would be selected less than the typical school lunch. More specifically, we will investigate whether the sample data provide strong evidence that the heather lunch is picked less than 50% of the time? The researchers found in their sample of 294 students that 134 picked the healthier option. The value of the sample proportion who selected the candy is therefore…arrow_forward
- Does posting calorie content for menu items affectpeople’s choices in fast-food restaurants? According to results obtained by Elbel, Gyamfi, and Kersh(2011), the answer is no. The researchers monitoredthe calorie content of food purchases for children andadolescents in four large fast-food chains before andafter mandatory labeling began in New York City. Although most of the adolescents reported noticing thecalorie labels, apparently the labels had no effect ontheir choices. Data similar to the results obtained showan average of M = 786 calories per meal with s =85 for n =100 children and adolescents before thelabeling, compared to an average of M = 772 calorieswith s = 91 for a similar sample of n = 100 after themandatory posting.a.

Suppose a hypothetical study is done for a different primate species, with one group given a resveratrol supplement and the other group given a placebo. We wish to see if there is evidence that resveratrol increases the mean metabolism rate for this species. (This exercise presents hypothetical data. We will see the results from the actual study later in this chapter.)
