We assume that our wages will Increase as we gain experience and become more valuable to our employers. Wages also increase because of inflation. By examining a sample of employees at a given point in time, we can look at part of the picture. How does length of service (LOS) relate to wages, The d. here (data.11.3.dat) is the LOS in months a. wages for 60 women who work in Indiana banks. Wages are yearly income divided by the number of weeks worked. We have multiplied wages by a constant for reasons of confidentiality. (a) Plot wages versus LOS. Consider the relationship and whether or not linear regression might be appropriate. (Do this on paper. Your Instructor may ask you to turn in this graph.)
(b) Find .e least-squares line. Summarize the significance test for .e slope. What do you conclude,
carefully what the slope .1. you about the relationship between wages and length of service.
IThis answer has not been graded yet.
(c1) Give a 9596 confidence ilerval for the slope.
