A sociological study was conducted to determine whether there is a relationship between the length of time blue- collar workers remain in their first job and the amount of their education. From union membership records, a random sample of persons was classified. The data are shown here.

a. Test the research hypothesis that the variable “years on first job’’ is related to the variable “years of education.’’

b. Give the level of significance for the test.

c. Draw your conclusions using a = .05.
