Step-by-step explanation:
We are given the following information:
The estimate regression equation for a model involving two independent variables and 10 observations follows:
where are the two independent variable and y is the dependent variable.
a) The regression line is of the form:
Comparing, we get,
These are the coefficients of respectively, and helps us to know the the significance of the independent variable in predicting the independent variable.
b) We have to estimate y when
