Question

In Hawaii, condemnation proceedings are under way to enable private citizens to own the property that their homes are built on. Until recently, only estates were permitted to own land, and homeowners leased the land from the estate. In order to comply with the new law, a large Hawaiian estate wants to use regression analysis to estimate the fair market value of the land. The following model was fit to data collected for n = 20 properties, 10 of which are located near a cove.

where Y = Sale price of property in thousands of dollars

X1 = Size of property in thousands of square feet

X2 = 1 if property located near cove, 0 if not

Using the data collected for the 20 properties, the following partial output obtained from Microsoft Excel is shown:

What is the slope for the independent variable Size and is it significant at an alpha of .05?

Question 25 options:

A. 12.2, no

B. 12.2, yes

C. 2.05, no

D. 2.05, yes

Explanation / Answer

from above output coefficient for variable slope is 12.2 and as p value is less than 0.05 level

therefore option B is correct
