  5. 5. Solution (3/6) y Question 4) y From table we conclude that a fact based movie has fewer stars than fiction based movies on an average. Type of movie Average Rating Type of movie Average Rating Fictional(including stars & non stars) 13.25 Fact based(including stars & non stars) 14.651 Fictional without stars 12.57 Fact based without stars 14.369 Fictional with stars 13.829 Fact based with stars 15.628
  6. 6. Solution (4/6) y Question 5) y From regression 5, 1 unit increase in previous program rating increases the rating of the movie by 0.1862 y Therefore, 2.5 increase in previous program rating increases the movie rating by = 2.5*0.1862 = 0.4655 y Question 6a & 6b) y From regression 5, 1 unit increase in the average rating of the competitors reduce the rating for CBC network by 0.2899 y Thus, 2 unit increase will reduce the rating for CBC by 0.5798
  7. 7. Solution (5/6) y Question 6b) y From case , 1 unit of rating represent 921,000 viewers y From regression 5, 1 unit increase in the average rating of the competitors reduce the rating for CBC network by 0.2899 y Therefore, for 1 unit increase in rating for ABN and BBS, their audience increase by 921,000 each and CBC audience decrease by 266,998 y Thus overall number of viewers increase
  8. 8. Solution (6/6) y Question 7a) y The regression does not provide enough data to y Question 7b) y For a fictional movie the average rating with star=13.829 and without star=12.57.
