DATA FILE

LOC1

(a) Write the model that you would use for a multiple regression to predict job stress from LOC, age, and gender.

(b) What are the parameters of your model?

(c) Run the multiple regression and give the estimates of the model parameters.

(d) Test the hypothesis that the coefficients for LOC, age, and gender are all zero. Give the test statistic with degrees of freedom

and the P-value. What do you conclude?

(e) What is the value of R2?

(f) Give the results of the hypothesis test for the coefficient for LOC. Include the test statistic, degrees of freedom, and the Pvalue. Do the same for the other two variables. Summarize your conclusions from these three tests.
