Answer:

#section 1

ls = []  

while True:

   score = float(input('Enter a New score or negative number to exit: '))

   if score < 0:

       break

   else:

       ls.append(score)

   

#section 2

average = sum(ls)/len(ls)

a = [num for num in ls if num >= average]

print('Total Scores Entered: ',len(ls))

print('Average score entered is: ',average)

print('Number of scores above average is: ',len(a))

print('Number of scores below average is:', len(ls)-len(a))

Explanation:

The programming language used is python 3.

#section 1

In this section, an empty list is initialized to hold all the values that will be inputted.

A while loop created which prompts the user to enter an input until a   negative value is entered. This while loop always evaluates to be true until a value less than 0 allows it to break.

Finally, all the scores are appended to the list.

#section 2

In this section the code gets the average by dividing the sum by the number of items in the list.

A new list 'a' is created to hold all the values that are greater than or equal to the average.

Finally, the results are printed to the screen.

I have attached an image with the example stated in your question.
