Refer to Exercise 9.19 (p. 487), in which the extent of retaliation against whistle blowers was investigated. Since salary is a reasonably good indicator of a person's power within an organization, the data of Exercise 9.19 can be used to investigate whether the extent of retaliation is related to the power of the whistle blower in the organization. The researchers were unable to reject the hypothesis that the extent of retaliation is unrelated to power. Do you agree'? Test using α = .05.
Exercise 9.19
Individuals who report perceived wrongdoing of a corporation or public agency are known as whistle blowers. Two researchers developed an index to measure the extent of retaliation against a whistle blower (Journal of Applied Psychology, 1986). The index was based on the number of forms of reprisal actually experienced, the number of forms of reprisal threatened, and the number of people within the organization (e.g., coworkers or immediate supervisor) who retaliated against them. The next table lists the retaliation index
(higher numbers indicate more extensive retaliation) and salary for a sample of 15 whistle blowers from federal agencies
a. Construct a scattergram for the data. Does it appear that the extent of retaliation increases, decreases, or stays the same with an increase in salary? Explain.
b. Use the method of least squares to fit a straight line to the data.
c. Graph the least squares line on your scattergram. Does the least squares line support your answer to the question in part a? Explain.
d. Interpret the y-intercept, , of the least squares line in terms of this application. Is the interpretation meaningful? e. Interpret the slope, x, of the least squares line in terms of this application. Over what range of x is this interpretation meaningful?
