A researcher has estimated a linear model to study the effect of weekly household income x, (in $100) on weekly household expenditure on food y, (in $). Using a sample of size /V = 40, she found that y = 83.42 + 10.21x;, R2 =0.384 (43.41) (2.09) and Ei=1(Vi-y)2 = 500,000 and the sample mean of X; is 19.605. Consider a hypothesis testing against Ho: the slope coefficient is 3.94. For this testing, the t-ratio is: a. do not reject Ho. Therefore we, at the 5% significance level, b. 4 C. 4.89 d. 2 e . 5 f. cannot do anything unless the significance level is 10%. g. accept H1 . h. reject Ho. i. 3 J. re-estimate the regression model using different data
