Question

A researcher has estimated a linear model to study the effect of weekly household income xi (in $100) on weekly household expenditure on food yi (in $). Using a sample of size N = 40, she found that yi_hat = 83.42 + 10.21xi, R^2 = 0.384 (43.41) (2.09) and sum(i=1 to N)(yi - y_bar)^2 = 500,000 and the sample mean of xi is 19.605. Consider a hypothesis testing against H0: the slope coefficient is 3.94. For this testing, the t-ratio is: Therefore we, at the 5% significance level, a. accept H1. b. reject H0. c. 3 d. 4 e. 2 f. 5 g. re-estimate the regression model using different data. h. do not reject H0. i. cannot do anything unless the significance level is 10%. j. 4.89
