|1. Suppose that we are interested in measuring the relationship between hourly wageand output productivity in the U.S economy. Variables hrwage, and outphr, denotethe average hourly wage and output productivity in the U.S economy for year t. Westart by estimating the model specification shown in equation (1) belowlog(hrwage) = -5.2 +1.53 log(outphr.),(0.033) (0.09)n = 41, R² = 0.967.i. Briefly comment on the value of the coefficient of determination, R², asshown in (2).ii. Test the null hypothesis that the elasticity of output productivity on hourlywage is zero against its two-tailed alternative at the 95% significance level.iii. Show how you can use the coefficient of determination, R², to test the nullhypothesis that B₁ is equal to zero against $₁0 at the 95% significancelevel. How does your answer compare to that in (ii)?

Given that the coefficient of determination R2 is 0.967. the regression equation is: log(hrwage) =…
