Based on the scatterplot and residual plot, what type of model is appropriate for comparing time and subscribers?
Answer
A
A logarithmic model is appropriate because the log of the number of subscribers was taken.
B
A linear model is appropriate because the residual plot shows a random scatter of points.
C
An exponential model is appropriate because the relationship between period and the log of subscribers is roughly linear and the residual plot shows no distinct pattern.
D
A power model is appropriate because the relationship between period and the log of subscribers is roughly linear.
