QUESTION 7 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 N = 40, she found that y=83.42 +10.21x, R²=0.384 (43.41) (2.09) and Σ(y₁ - 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: Therefore we, at the 5% significance level, a. cannot do anything unless the significance level is 10%. b. do not reject Ho. C. 3 d. accept H₁. e. 4.89 f. 4 8.5 h.reject Ho. 1. 2 j. re-estimate the regression model using different data.
