Answer :
Using a linear regression calculator, the regression equation which models the house price for the data given is ŷ = 0.0807X - 3.4286
Given the data :
Square feet ____House price
1400 __________ 108
1700 __________ 133
1500 __________ 120
Using a linear regression calculator , the equation which models the data is :
- ŷ = 0.0807X - 3.4286
Where :
slope of the equation is = 0.0807
Intercept = 3.4286
