Question

Home Size and Value. The data from Exercise $14.38$ for home size (in square feet) and assessed value (in thousands of dollars) for the same homes as in Exercise $14.101$ are on the WeissStats site. Specified value of the predictor variable: $3000sq.ft$.

Short answer

The assumption $3$for the regression inferences is violated for the variables value and home size.
From part (a), it is clear that the assumptions for the regression inferences are violated. Hence, from part (b) to part (f) cannot be calculated.

Step-by-step solution

Given information

To determine whether the conditional mean and predated value t-interval procedures can be applied to data.

Explanation

Given that,

Calculation:
Check whether reasonably to apply the conditional mean and predated value t-interval procedure to data by using Exercise 14.38.

• The residual plot clearly shows that the residuals are in the horizontal band.
• The normal probability plot of residuals shows that the residuals deviate from the linear pattern.
• As a result, for the variables value and home size, assumption 3 for regression inferences is violated.
• Part (a) clearly shows that the assumptions for regression inferences are violated. As a result, the distance from part (b) to part (f) cannot be calculated.

Conclusion

As a result, for the variables value and home size, assumption 3 for regression inferences is violated.

Part (a) clearly shows that the assumptions for regression inferences are violated. As a result, the distance from part (b) to part (f) cannot be calculated.
