A real estate developer wishes to study the relationship between the size of home a client will purchase (in square feet) and other variables. Possible independent variables include the family income, family size, whether there is a senior adult parent living with the family (1 for yes, 0 for no), and the total years of education beyond high school for the husband and wife. The sample information is reported below.

Family	SqrFt	Income	Size	Senior	Education
1	2240	60.8	2	0	4
2	2380	68.4	2	1	6
3	3400	104.5	3	0	7
4	3360	89.3	4	1	0
5	3000	72.2	4	0	2
6	2900	114	3	1	10
7	4100	125.4	6	0	6
8	2520	83.6	3	0	8
9	4200	133	5	0	2
10	2800	95	3	0	6

a. Develop an appropriate multiple regression equation using stepwise regression. (Use Excel data analysis and enter number of family members first, then their income and delete any insignificant variables. Leave no cells blank - be certain to enter "0" wherever required. R and R² adj are in percent values. Round your answers to 3 decimal places.)
