Yuliya22 [10]

The table is missing in the question. The table is attached below.

Solution :

Let X = appraised value

Y = area (square feet)

The regression line is given by :

$\hat y = b_0+b_1X$

$b_1=\frac{n\sum XY-\sum X \sum Y}{n \sum X^2-(\sum X)^2}$

$=\frac{15(5964990)-(2157)(33370)}{15(404799)-(2157)^2}$

$=12.3267$

$b_0=\frac{\sum Y}{n}-b_1\frac{\sum X}{n}$

$=\frac{33370}{15}-\left(12.3267 \times \frac{2157}{15}\right)$

$b_0=452.0841$

The regression line is :

$\hat Y = 452.0841+12.3267 X$

To estimate the error variance, we have:

Error variance, $\sigma =\sqrt{\frac{\sum (Y-\hat Y)^2}n-2{}}$

$=\sqrt{\frac{587682.3}{15-2}}$

$=212.6178$
