The numbers of hours of video uploaded to YouTube per minute are shown in Table 73 for various years.

Let y be the video upload rate (number of hours of video uploaded per minute) to YouTube at x years since 2005.
a. Construct a scatterplot by hand.
b. Graph the model = 2.6(1.59)x by hand on the scatterplot. Does the model come close to the data points?
c. What is the base b of the model? What does it mean in this situation?
d. Use your model to estimate the video upload rate to YouTube in 2014. The actual rate was 300 hours of video per minute. Compute and interpret the residual.
e. A student says your model should estimate the 2014 video upload rate well because the model fits the data shown in Table 73 so well. What would you tell the student?
