Question

Question 23 (1 point) Suppose that in a certain neighborhood, the cost of a home is proportional to the size of the home in square feet. If the regression equation quantifying this relationship is found to be cost) - 93.817 size) 547.798. what does the slope indicate? 1) When size increases by 1 square foot, cost increases by 547.798 dollars. 2) We are not given the dataset, so we cannot make an interpretation 3) When size increases by 1 square foot, cost increases by 93.817 dollars. 4) When cost increases by 1 dollar, size increases by 93.817 square feet. 5) When cost increases by 1 dollar, size increases by 547.798 square feet.

Explanation / Answer

23.ans > 3)

24. ans-> 4)

25. Since P-value for coefficient of food quality = 0.0205 < 0.05, so we reject H0 at 5% level of significance and we can conclude that

ans -> 1) The slope significantly differs from 0

26. ans-> 3)
