This script demonstrates basic NumPy array manipulation:
- Updates product prices by assigning a value of 20 to all prices greater than 10.
- Modifies product ratings for two categories over three criteria by setting the last two criteria of the first category to 9.
- Prints the updated prices and ratings arrays.
