Question 2

Suppose a researcher gathered survey data from 19 employees and
asked the employees to rate their satisfaction on a scale from 0 to 100 ( with
100 being perfectly satisfied). Suppose the following data represent the
results of the survey. Assume that the relationship with supervisor is rated on
a scale from 0 to 50 (0 represents a poor relationship and 50 represents an
excellent relationship); overall quality of the work environment is rated on a
scale from 0 to 100 (0 represents poor work environment and 100 represents an
excellent work environment); and opportunities for advancement is rated on a
scale from 0 to 50 (0 represents no opportunities and 50 represents excellent
opportunities).

Answer the following questions:

A) What is the regression formula?

B) How reliable do you think the estimates will be based on this
formula? Explain your answer by citing the relevant metrics.

C) Are there any variables that do not appear to be good
predictors of job satisfaction? How can you tell?

D) If anew employee reports that her relationship with her
supervisor is 40, rates her opportunities for advancement to be at 30, finds
the quality of the work environment to be at 75, and works 60 hours per week,
what would you expect her job satisfaction score to be?
