Which is the best estimate of the residual when x = 4? –2 2 2.5 –2.5

-2.5

Step-by-step explanation:

First, we need to know what is the residual is

The residual is the vertical distance between the regression line and a data point. If the distance is positive, the point is above the line and vice versa if the distance is negative, the point is below the point.

In this question, at x= 4 the we have the value is 2 but the value on the line is 4.5 so the vertical distance is:

2-4.5 =-2.5

As the data point lie below the regression line. hence the residual value will be negative. So we choose -2.5

Hope it will find you well.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
