Question

Find the residual values, and use the graphing calculator tool to make a residual plot.

Answer 1

Answer-

D. No, the points are in a curved pattern.

Solution-

The difference between the observed or given value of the dependent variable and the predicted value is called the residual. Each data point has one residual.

$Residual\ value= Given\ value - Predicted\ value$

If the points in a residual plot are randomly dispersed around the horizontal or x-axis, a linear regression model is appropriate for the data. Otherwise, a non-linear model is more appropriate.

Plotting a graph, by taking the residual values on ordinate and values of given x on abscissa, a non-random U pattern is obtained.

So a non-linear model will be a better fit for this data set.

Answer 2

Answer:

Does the residual plot show that the line of best fit is appropriate for the data?

No, the points are in a curved pattern. it is a on edg
