Remove Overall Mean Bias

1. Modify the CustomerMeans.java and MovieMeans.java programs by computing the average of the customer ratings after subtracting the Overall Mean = 3.604289964420661 from each rating.
2. Now modify your Part 3 programs to use these new Customer and Movie means. However, at the end add Overall Mean = 3.604289964420661 back to the prediction.
