1. Using the data for CBC movies:

a. Use a line graph of the monthly average ratings for CBC for the year. Note that there are multiple ratings data for the months; you will need to calculate an average for each month first, and then plot the averages.

b. After you use the graph, fit a linear trend line and a 2nd order polynomial trend line, displaying the formula and the r-squared.

c. Explain if you can use this time series data to forecast the ratings of upcoming months. Which forecasting method is better? How accurate can you expect this forecast to be?
