Will Give good review/rating for correct answer/explanation below. Thank you!
other, variable costs.) Complete parts a through 8 . Click the icon to view the data table of home prices and sizes. (a) Is the simple regression model a reasonable description of the association between the two variables? In particular, consider the conditions needed for the reliable use of the SRM. A. All the conditions for the SRM are satisfled. B. The variances of the residuals are eignificantly different. C. The residuals are not normal. D. The association between y and x is not linear. E. The errors are not independent. F. There are obvious lurking variables. (b) Give a 95% confidence interval for the fixed cost (the portion of the cost that does not change with the size of the home) associated with these home prices, along with a brief interpretation. The fixed cost is between $ and $ (Round to the nearest hundred dollars as needed.) Choose the correct interpretation below. A. The fixed cost is zero. B. The fixed cost might be zero, negative, or considerable. C. The fixed cost is negative. D. The fixed cost is positive. (c) Glve a 95% confldence interval for the varlable costs (the cost determined by the number of square feet), along with a brief interpretation. The variable costs are from $ to S/ (Round to the nearest dollar as needed.) Data table Choose the correct interpretation below. A. The variable costs are zero. B. The variable costs are positive. C. The variable costs are negative. D. The variable costs might be zero, negative, or considerable. (d) How much might a buyer pay, per square foot, for a specific home with 3000 square feet? On average, the buyer would expect to pay between $ and $ per square foot. (Round to the nearest cent as needed.) (e) How much in total might a buyer pay for the 3000 -square-foot home? On average, the buyer would expect to pay between $ and $ for a 3000 -square-foot home. (Round to the nearest thousand as needed.) other, variable costs.) Complete parts a through 8 .
