# Calculate the score # Decomment and complete the function 'score' #Decomment the following line print('Score = {:.3f}'.format(score(F_1, F_2, a, F_1_hat, F_2_hat, a_hat)))

Sure, I can help you with that!

The `score` function takes six arguments: `F_1`, `F_2`, `a`, `F_1_hat`, `F_2_hat`, and `a_hat`. Without knowing the specifics of what these variables represent, it's difficult for me to provide an exact implementation of the `score` function. However, the general idea is that you need to calculate some sort of score based on these input values.

Here's an example implementation of the `score` function that calculates a simple score based on the input values:

def score(F_1, F_2, a, F_1_hat, F_2_hat, a_hat):
    score = (F_1 * F_2 * a) / (F_1_hat * F_2_hat * a_hat)
    return score

This implementation simply multiplies `F_1`, `F_2`, and `a` together, and divides the result by the product of `F_1_hat`, `F_2_hat`, and `a_hat`. The resulting value is returned as the score.

To use this implementation, you can uncomment the `print` statement and call the `score` function with your input values:

print('Score = {:.3f}'.format(score(F_1, F_2, a, F_1_hat, F_2_hat, a_hat)))

This will print the score with three decimal places.
