Job growth. Fortune Magazine publishes the top 100 companies to work for every year. Among the information listed is the percentage growth in jobs at each company. The output below shows the regression of job growth (%) in the current year on job growth from two years prior. (One outlier has been omitted.) Job Growth in the more recent year is the response variable.

Dependent variable is: Job Growth R-squared = 5.7%

s = 0.0738 with 68 - 2 = 6 degrees of freedom Variable Coeff SE(Coeff) t-Ratio P-Value Intercept 0.0628 0.009 7.00 60.0001 Job Growth 0.2 0.100 2.00 0.0498

a) State the hypotheses about the slope (both numerically and in words).

b) Assuming that the assumptions for inference are satisfied, perform the hypothesis test and state your conclusion in context.

c) Explain what the R-squared in this regression means.

d) Do these results indicate that, in general, companies with a higher job growth in the earlier year had higher job growth in the later year? Explain.
