The residual plot shows the residuals for a student’s GPA and daily amount of time spent on social media (in hours). Which statement best assesses the linearity of the relationship between GPA and daily time on social media if the scatterplot appears to be reasonably linear?
Answer
A
Because the residual plot has a clear pattern, rather than the desired random scatter, it is appropriate to use the line of best fit to predict GPA based on daily time on social media.
B
Because the residual plot has a clear pattern, rather than the desired random scatter, it is not appropriate to use the line of best fit to predict GPA based on daily time on social media.
C
Because the residual plot has no obvious pattern, it is appropriate to use the line of best fit to predict GPA based on daily time on social media.
D
Because the residual plot has no obvious pattern, it is not appropriate to use the line of best fit to predict GPA based on daily time on social media.
