A researcher wished to find out whether the perceptions of a persons height depends on that person’s perceived status. A random sample of army inductees was selected and equally divided into four groups. An actor gave a short address to each group separately, extollng the joys of army life. For the first group, the actor was dressed as a private; for the second, as a sergeant; for the third, as a captain, and, finally, for the fourth grup, as a Colonel. The inductees were asked to fill out a questionnaire evaluating the speech. Among the questions was one asking for an estimate of the lecturer’s height.

A large group of workers is divided into three departments: those who work in special operations, those who work on the main floor, and those who work in management. Strep throat has been going around and a health inspector would like to know if there is a relationship between department and having strep throat. She selects a random sample of 100 workers and classifies each one according to their department and whether they have strep throat. The data are displayed in the table. The health inspector would like to know if these data provide convincing evidence that the distribution of strep throat status differs across the departments in the population of all workers of this large company. What is the appropriate inference procedure? chi-square test for goodness of fit because the data come from one random sample chi-square test for homogeneity because the data come from independent random samples chi-square test for association/independence because the data come from one random…
Nationally, 83% of Americans have earned a high school diploma. We want to see if the proportion of Pennsylvania high school students who have a high school diploma is greater than 83%. Suppose a representative sample of 225 Pennsylvanians is taken and each is asked if they have earned a high school diploma. 198 of the 225 Pennsylvanians were found to have earned a high school diploma. Which of the following should we conclude? Select one: a. The proportion of Pennsylvanians with a high school diploma is equal to 0.83. b. The proportion of Pennsylvanians with a high school diploma is greater than 0.83. c. 0.83 is a plausible value for the proportion of Pennsylvanians with a high school diploma. d. The proportion of Pennsylvanians with a high school diploma is different from 0.83.
The survey included questions on ticketing, boarding, in-flight service, baggage handling, pilot communication,and so forth. Twenty-five questions offered a range of possible answers: excellent, good, fair, or poor. A response of excellent was given a score of 4, good a 3, fair a 2, and poor a 1. These responses were then totaled, so the total score was an indication of the satisfaction with the flight. The greater the score, the higher the level of satisfaction with the service. The highest possible score was 100. Brunner randomly selected and surveyed passengers from the four airlines. Below is the sample information. Is there a difference in the mean satisfaction level among the four airlines? Use the .01 significance level.
A study was conducted to investigate whether local car mechanics charge women more than men for a transmission repair. The researcher selected randomly one man and one woman from everyone who had used the same mechanic for the same transmission repair. The process was repeated for a total of seven selected randomly cars. The repair prices and the differences are shown in the table.
