The data below contains sale price, size, and land-to-building ratio for 10 large industrial properties {r} saleprice <- read.csv("https://www.siue.edu/~jpailde/saleprice.csv") saleprice i) Construct a scatterpot for sale price versus size and sale price versus land-to-building ratio`. Be sure to fit regression lines on the scatterplots. ii) Use the `Im function to estimated the equations of each regression model for sale price versus size` and `sale price versus land-to-building ratio`. iii) Check the error model assumption visually by constructing a residual plot and QQplot of the residuals for the two models. iv) Estimate the population regression slope of each model (line) by constructing 95\% confidence interval. Give a brief interpretation of the esimated slope in the context of the problem. v) Perform a hypothesis test on the regression slope of each model (line), use a 5\% level of significance. Given an appropriate conclusion.

b) Next, we investigate whether the energy production mainly depends on the electricity supplied. To examine that we carry out a regression model and the results are given in Exhibit 11 below. We define the variables as follows: Dependent variable: total_energy = is the total energy production of different sources (GWh) Independent variable: Electricity supplied = monthly electricity supplied (GWh) i) From Exhibit 11, state the intercept coefficient value. Is it meaningful? Explain. ii) Give an interpretation of the slope coefficient given in Exhibit 11. iii) From the output in the Exhibit 11 above, test if the monthly electricity supply significantly increases the energy production in Australia.
