Answer:
a)
b) y = 289.815
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
The equation represents a circle centered at (3,5) and passing through the point (-2,9) will be,
What exactly is a circle?
It is a point locus drawn equidistant from the center. The radius of the circle is the distance from the center to the circumference.
Given data;
The Centre of the circle is,(h,k)=(3,5)
The circle traverses (-2,9). Consequently, the radius of the circle r is equal to the separation between (3, 4) and (-2,1).
So radius;
Now equation of the circle with center (h,k) and radius r is
Hence equation represents a circle that will be,
