3. Suppose that a researcher estimates a consumptions function and obtains the following results C=15+0.81Ya (3.1) (18.7) n = 19 r² = 0.99 where C=Consumption, Yd-disposable income, and numbers in the parenthesis are the 't-statistics' a. Test the significance of the slope parameter Using t-test b. Determine the estimated standard deviations of the parameter estimates c. Construct 95% confidence interval for intercept term and test its significance using the constructed interval
