Chapter 10.3, Problem 10.29ACB
Package design influences taste. Can the package design of a food product, along with accompanying sounds, influence how the consumer wilt rate the taste of the product? A team of experimental psychologists reported on a study that examined how rounded or angular package shapes and high- or low-pitched sounds can convey information about the taste (sweetness and sourness) of a product (Food Quality and Preference, June 2014). Study participants were presented with one of two types of packaging displayed on a computer screen monitor: rounded shape with a low-pitched sound or angular shape with a high-pitched sound Assume that half of the participants viewed the rounded packaging and half viewed the angular packaging. After viewing the product, each participant rated whether the packaging was more appropriate for either a sweet- or a sour-tasting food product. A summary of the results (numbers of participants) for a sample of 80 participants is shown in the following
- a. Specify the null and alternative hypotheses for testing whether the package design and sound pitch combination influences the consumer’s opinion on the product taste.
- b. Assuming the null hypothesis is true, find the expected number in each cell of the table.
- c. Use the expected numbers and observed counts in the table to compute the chi-square test statistic.
- d. The observed significance level (p-value) of the test is approximately 0. (You can verify this result using statistical software.) For any reasonably chosen value of α, give the appropriate conclusion.

A researcher is interested in examining whether the location that a person lives is related to the number of hours that they spend on the internet each week. The researcher collected data from a sample of 30 participants who were classified in one of three groups: (1) 10 people who live in an urban setting, (2) 10 people who live in a suburban setting, and (3) 10 people who live in a rural setting. Each participant reported the number of hours they spend on the internet in a typical week (the dependent variable). The researcher found the following descriptive statistics:
Urban participants reported an average of 8.9 hours of internet use per week with a standard deviation of 2.77.
Suburban participants reported an average of 12.7 hours of internet use per week with a standard deviation of 4.88.
Rural participants reported an average of 9.8 hours of internet use per week with a standard deviation of 2.82.

- A research article describes a study that investigated the relationship between depression and chocolate consumption. Participants in the study were 931 adults who were not currently taking medication for depression. These participants were screened for depression using a widely used screening test. The participants were then divided into two samples based on their test score. One sample consisted of people who screened positive for depression, and the other sample consisted of people who did not screen positive for depression. Each of the study participants also completed a food frequency survey. The researchers believed that the two samples were representative of the two populations of interest—adults who would screen positive for depression and adults who would not screen positive. The paper reported that the mean number of servings per month of chocolate for the sample of people that screened positive for depression was 8.37, and the sample standard deviation was 14.85.

The company wants to know whether the truck appearance, miles per gallon (MPG), or fixed price most influence the consumer’s buying decision. A population sample of 500 individuals, both male and female, will be surveyed and the data will be presented in a table. The company wants to know if there is a pattern to these preferences in order to better predict consumer behavior. Specifically, the firm wants to know if there is any difference in proportion using the three different criterions to purchase the given car based on gender.

In the article, Mehl, Vazire, Ramirez-Esparza, Slatcher, & Pennebaker (2007) report the results of a study of 396 men and women. Each participant wore a microphone that recorded every word he or she uttered. The researchers counted the number of words uttered by men and women and compared them. The data below are fictional but they re-create the pattern that Mehl and colleagues observed: Men: 16,345 17,222 15,646 14,889 16,701 Women: 17,345 15,593 16,624 16,696 14,200 Conduct steps for hypothesis testing.

- In a study examining the effect of humor on interpersonal attractions, McGee and Shevlin (2009) found that a man’s sense of humor had a significant effect on how he was perceived by women. In the study, female college students were given brief descriptions of a potential romantic partner and then rated the attractiveness of the male on a scale from 1 (low) to 7 (high). The fictitious male was described positively as being single, ambitious, and having good job prospects. In one condition, the description also said that he had a great sense of humor. The results showed that the description was rated significantly higher when “a sense of humor” was included. To examine this effect further, a researcher selected a sample of n = 16 college males and asked them to read a brief description of a female and then rate the attractiveness of the woman in the description. The description had been used in previous research but was modified by adding a statement describing a good sense of humor.…arrow_forwardEmoticons, like ☺ and ☹, are helpful for expressing emotion in communications that otherwise have limited emotional content (e.g., emails, text messages, and social media posts). Derks, Bos, and von Grumbkow (2007) conducted an independent sample experiment to study the effect of social context and emotion on the use of emoticons. Four groups of participants were instructed to use an internet chat program and the researchers measured the number of emoticons produced by participants. The first group of participants was instructed to communicate about an emotionally positive task (e.g., organizing a group project). The second group of participants was instructed to communicate about an emotionally positive socio-emotional event (e.g., brainstorming about a friend’s birthday). The third group was treated like the first group, except that task was emotionally negative and the fourth group was treated like the second group, except that the socio-emotional event was emotionally negative.…arrow_forwardA study examined the relationship between a nurse's assessment of a patient's facial expression and his or her self-reported level of pain. Data for 89 patients are summarized below: Self-Report Facial Expression No Pain Pain No Pain 17 40 Pain 3 29 We'd like to determine if there is evidence of an association between a facial expression that reflects pain and self-report pain, because dementia patients do not always give a verbal indication that they are in pain.

- Study 2: Pill Appearance and Perceived Pain. Does the shape or color of a pain pill influence its effectiveness? Although logically it shouldn’t, whether we believe a drug will work does have a powerful effect on our perceptions (e.g., placebo effect). In this experiment, 4 groups of adult patients were given the same amount of Advil after dental surgery for pain relief, but the color and shape of the pill varied. Researchers hypothesized that an unusual shape or color would lead people to believe the pills were new and special and thus would expect them to be more effective than common round, white pills. Researchers also wanted to know if there is an interaction between shape and color Data Labels ShapePill {1=Round; 2=Diamond} ColorPill {1=White; 2=BlueGreen} Gender {0=Woman; 1=Man; 2=Nonbinary person) Descriptions of the Variables and Descriptive Statistics: Referring to the JASP output, and using sentences, present the descriptive statistics of each group: for example:…arrow_forwardA study was conducted to explore the prevalence and impact of sleep problems on various aspects of people's lives.

This occurs in varied situations such as shelf positions when shopping, filling out a questionnaire, and even when choosing a preferred candidate during a presidential debate. In this experiment, five identical pairs of white socks were displayed by attaching them vertically to a blue background that was then mounted on an easel for viewing. One hundred participants from the University of Chester were used as subjects and asked to choose their preferred pairs of socks. In choice situations of this type, subjects often exhibit the "center stage effect," which is a tendency to choose the item in the center. In this experiment, 34 subjects chose the pair of socks in the center. Are these data evidence of the "center stage effect"? STATE: Are the students choosing pairs of socks randomly?
