Question
Part 1
1.What is the average rating for all CBC movies?
2.How about ABN movies and BBS movies?
3.Include a table that shows the average and the other descriptive statistics for the ratings of the three networks (one column for each network).
4.Comment on which network is doing best and what you learn from the other key metrics in the table.
Part 2
1. Create 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 and then plot the averages.
2. After you create the graph, fit a linear trend line, displaying the formula and the r-squared.
3. Explain to the executives if, and how, you can use this time series data to forecast the ratings of upcoming months. How accurate can you expect this forecast to be?
Part 3
1. Should the CBC hire celebrities for their movies? To answer this question, run a hypothesis test to see if there is a significant difference between the ratings of movies with celebrities versus movies without celebrities.
2. Use the data for CBC movies only and use a 95% confidence. Explain your answer-do not simply say yes or no without referring to the relevant figures.
Part 4
1. Which has more impact on a movie's rating, one that is fact based or that it has one celebrity?
2. How much does each of these factors change the ratings?
3. Do you expect a fact-based movie that does not have any celebrities to get better ratings than a fiction movie with one celebrity?
4. Run a multiple regression where the dependent variable is ratings and the independent variables are celebrity and fact.
5. Use data from all networks, not just CBC movies. How well does this regression analysis explain the ratings? Justify your answers based on the results.
