In 2018, a consumer goods giant had more than 20 brands with more than $1 billion in annual sales. How does the company create so many successful consumer products? They effectively invests in
research and development to understand what consumers want. One method used to determine consumer preferences is called conjoint analysis. Conjoint analysis allows a company to ascertain the
utility that a respondent in the conjoint study places on a design of a given product. The higher the utility, the more valuable a respondent finds the design. Suppose we have conducted a conjoint study
and have the following estimated utilities (higher is preferred) for each of three different designs for a new whitening toothpaste.

Elementary and high school teachers were surveyed and were asked if they felt rewarded and satisfied with their jobs. Of the 350 elementary school teachers, 142 said they were satisfied with their jobs. Of the 243 high school teachers, 119 said they were satisfied with their jobs. Because of the number of students in elementary classrooms, it is believed that the proportion of elementary school teachers satisfied with their jobs is less than the proportion of high school teachers who are satisfied with their jobs.
Let
population 1=proportion of elementary school teachers satisfied with their jobs
population 2=proportion of high school teachers satisfied with their jobs
1. What is the alternative hypothesis?
2. What best describes the hypothesis test to be performed?
3. What is the value of the test statistic? Use 2 decimal places
4. What is the critical value if a 0.01 significance level is used?

A third criteria of location was initially considered, but then the student recognized that it is only for about a year, and applications were only made to acceptable schools. The student is currently enrolled in the first university, which is rated as a 5 for academic rank and a 7 for cost. The second is a larger outof-state public university, which is rated as a 7 for academic rank and a 6 for cost.

- Researchers constructed two test sheets, each sheet including 20 photos of the faces of dog–owner pairs taken at a dog lovers' field festival. The 20 sets of dog–owner pairs on the two sheets were equivalent with respect to breed, diversity of appearance, and gender of owners. On the first sheet, the dogs were matched with their owners, while on the second sheet, the dogs and owners were deliberately mismatched. Three experiments were conducted, and in all experiments, subjects were asked to "choose the set of dog–owner pairs that resemble each other, Sheet 1 or Sheet 2," and were simply told the aim of the research was a "survey on dog–owner relationships." In the first experiment, the original sheets were shown to subjects; in the second experiment, just the "mouth region" of the owners was blacked out in all the pictures on both sheets; in the third experiment, just the "eye region" of the owners was blacked out.

Specifically, this psychologist thinks that introverts are more creative than extraverts. The researcher gives a personality test to a group of 16 university students and then separates them based on the assessment results into 2 groups: the extraverts and the introverts. The participants are then asked to write a short story which is rated on creativity by a well-known author. The creativity scores range from 0 to 20 on an interval scale, where higher scores indicate greater creativity. The results are shown in Table 2.
