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 Zi=](Vi- V)2 = 500,000 and the sample mean of X is 19.605. Choose the wrong statement. a. The estimated variance of the slope estimator is (2.09)2. Ob. The standard deviation of the intercept coefficient is 43.41. Oc. We would reject Ho: "the slope parameter is zero" at the 5% level. d. If a household has a weekly income of 1000 dollars, the food expenditure would be 83.42 + 10.21x10 with some uncertainty. e. The sample correlation coefficient between the household income and the household expenditure on food is positive
