Suppose that a researcher estimates a consumption function and obtains the

following results:

C=15+0.81Yd n=19 R2=0.99

(3.1) (18.7)

where C=Consumption, Yd=disposable income, and numbers in the parenthesis are the

‘t-ratios’

a. Test the significant of Yd statistically using t-ratios

b. Determine the estimated standard deviations of the parameter estimates
