Chapter 10: Q. 26 (page 670)

A large university is considering the establishment of a schoolwide recycling program. To gauge interest in the program by means of a questionnaire, the university takes separate random samples of undergraduate students, graduate students, faculty, and staff. This is an example of what type of sampling design?

(a) Simple random sample

(b) Stratified random sample

(c) Convenience sample

(d) Cluster sample

(e) Systematic sample

Short Answer

Expert verified

This is an example of (b) Stratified random sample .

Step by step solution

01

Given information

We are given that a large university is considering the establishment of a schoolwide recycling program. The university takes separate random samples of undergraduate students, graduate students, faculty, and staff . We have to find that what type of sampling design, this example belongs to.

02

Simplify

As we know the overall population is divided into sub populations based on a variable called strata. that is undergraduate students, graduate students, faculty, and staff .

Therefore,this example will be Stratified Random Sample.

To study the long-term effects of preschool programs for poor children, researchers designed an experiment. They recruited 123children who had never attended preschool from low-income families in Michigan. Researchers randomly assigned 62of the children to attend preschool (paid for by the study budget) and the other 61to serve as a control group who would not go to preschool. One response variable of interest was the need for social services for adults. In the past 10years, 38children in the preschool group and 49 in the control group have needed social services.4 1. Does this study provide convincing evidence that preschool reduces the later need for social services? Carry out an appropriate test to help answer this question.

46. Happy customers As the Hispanic population in the United States has grown, businesses have tried to understand what Hispanics like. One study inter-viewed a random sample of customers leaving a bank. Customers were classified as Hispanic if they preferred to be interviewed in Spanish or as Anglo if they preferred English. Each customer rated the importance
of several aspects of bank service on a 10-point scale. Here are summary results for the importance of 鈥渞eliability鈥� (the accuracy of account records and so on):

(a) The distribution of reliability ratings in each group is not Normal. A graph of the data reveals no outliers. The use of two-sample t procedures is
justified. Why?
(b) Construct and interpret a 95% confidence interval for the difference between the mean ratings of the importance of reliability for Anglo and
Hispanic bank customers.
(c) Interpret the 95% confidence level in the context of this study.

Many new products introduced into the market are targeted toward children. The choice behavior of children with regard to new products is of particular interest to companies that design marketing strategies for these products. As part of one study, randomly selected children in different age groups were compared on their ability to sort new products into the correct product category (milk or juice). Here are some of the data:

Age groupNNumber who sorted correctly4- to 5-year-olds50106- to 7-year-olds5328

Are these two age groups equally skilled at sorting? Use information from the Minitab output below to support your answer.

Credit cards and incentives A bank wants to know which of two incentive plans will most increase the use of its credit cards. It offers each incentive to a group of current credit card customers, determined at random, and compares the amount charged during the following six months.

(a) Is this a problem with comparing means or comparing proportions? Explain.

(b) What type of study design is being used to produce data?

Dr Teresa Amabile conducted a study involving 47college students, who were randomly assigned to two treatment groups. The 23students in one group were given a list of statements about external reasons (E) for writing, such as public recognition, making money, or pleasing their parents. The 24students in the other group were given a list of statements about internal reasons (I) for writing, such as expressing yourself and enjoying playing with words. Both groups were then instructed to write a poem about laughter. Each student鈥檚 poem was rated separately by 12different poets using a creativity scale. The 12poets鈥� ratings of each student鈥檚 poem were averaged to obtain an overall creativity score. We used Fathom software to randomly reassign the 47subjects to the two groups 1000times, assuming the treatment received doesn鈥檛 affect each individual鈥檚 average creativity rating. The dot plot shows the approximate randomization distribution of x1-xE

(a) Why did researchers randomly assign the subjects to the two treatment groups?

(b) In the actual experiment, x1-xE=4.15. What conclusion would you draw? Justify your answer with appropriate evidence.

(c) Based on your conclusion in part (b), could you have made a Type I error or a Type II error? Justify your answer.
