Chapter 1, Problem 1.33ACI
Accounting and Machiavellianism. Behavioral Research in Accounting (January 2008) published a study of Machiavellian traits in accountants. Machiavellian describes negative character traits that include manipulation, cunning, duplicity, deception, and bad faith. A questionnaire was administered to a random sample of 700 accounting alumni of a large southwestern university; however, due to nonresponse and incomplete answers, only 198 questionnaires could be analyzed. Several variables were measured, including age, gender, level of education, income, job satisfaction score, and Machiavellian (“Mach”) rating score. The research findings suggest that Machiavellian behavior is not required to achieve success in the accounting profession.
- a. What is the population of interest to the researcher?
- b. What type of data (quantitative or qualitative) is produced by each of the variables measured?
- c. Identify the sample.
- d. Identify the data-collection method used.
- e. What inference was made by the researcher?
- f. How might the nonresponses impact the inference?

A company is considering an organizational change which entails adopting the use of self-managed work teams which they hope will lead to higher levels of employee satisfaction. In order to assess the attitudes of employees of the company towards this change a sample of 250 employees was selected and asked whether they favor the institution of self-managed teams. Three responses were allowed: favor, neutral or oppose. The observed frequency of the results of the survey are shown below:

A researcher investigated whether a father's level of optimism was predictive of his son's optimism as a young adult. Twenty (20) fathers and sons who agreed to participate in the study were administered a scale measuring their current level of optimism (the scale ranged from 10 to 50), with higher scores indicating greater optimism.
We have a random sample of workers from a large firm. In 2017, the firm ran a training program. Some workers did the training program, others did not. The firm now wants to assess the effect of the training on earnings.
We use the following model to estimate the effect of a training program on annual earnings in 2018:
ln(earn2018)=β0+β1train+β2ln(earn2016)+β3educ+β4exper+u
where
earn2018 = individual total annual earnings in 2018 in dollars
train = a dummy variable that takes the value 1 if the individual worker did the training in 2017 and 0 otherwise
earn2016 = individual total annual earnings in 2016 in dollars
educ = the individual's years of education
exper = the individual's years of experience
We find:
ln(earn2018)^= 11.672 + 0.041train + 0.821ln(earn2016) + 0.037educ + 0.012exper

- Do waiters or waitresses earn larger tips To answer this Do waiters or waitresses earn larger tips? To answer this question, a restaurant consultant undertook a preliminary study. The study involved measuring the percentage of the total bill left as a tip for one randomly selected waiter and one randomly selected waitress in each of 50 restaurants during a 1-week period.

The airplane has 50 seats, but Allegiant is considering accepting more reservations than seats because sometimes passengers do not show up for their flights, resulting in empty seats. The PassengerAppearance worksheet in the file Overbooking contains data on 1,000 passengers showing whether or not they showed up for their respective flights. In addition, Allegiant has conducted a field experiment to gauge the demand for reservations for the current flight. During this experiment, they did not limit the number of reservations for the flight to observe the uncensored demand. The following table summarizes the result of the field experiment.

- Investigators enrolled 2,100 women in a study and followed them monthly to determine the incidence rate of heart disease. After one month of the first period of observation, none had a new diagnosis of heart disease, but 100 had died. In the second observation period which lasted for three months, 1 had a new diagnosis of heart disease within 1 month, and another 99 died within 2 months. In the third observation period which lasted for four months, another 7 had new diagnoses of heart disease and 793 died within 2 months. Calculate the incidence rate of heart disease among this cohort.

To test this statement, the retailer took a random sample of 185 of the salesman's cellular phones and 150 of the competitor's cellular phones. The retailer found that 22 of the salesman's cellular phones and 11 of the competitor's cellular phones were defective. Does the retailer have enough evidence to reject the salesman's claim?
