Create a function called avgSumOfSquares that expects no arguments. Instead, this function gets its input from the user at the keyboard. The function asks the user to enter a series of numbers, one at a time. The user types end to indicate that there are no more numbers. The function computes the average of the sum of the squares of all the values entered. For example, given the values 6, -3, 4, 2, 11, 1, and -9, the sum of the squares would be (36 + 9 + 16 + 4 + 121 + 1 + 81) = 268. The average of the sum of squares would then be 268/7 = 38.285714285714285. The function then prints the average of the sum of the squares and returns that average. However, if end is entered before any values are entered, the function notifies the user that no numbers were entered and returns None. You may assume the user inputs are valid: they will either be a number or the string end. Here are some examples of how your function should behave:

>>> avgSumOfSquares()

Enter next number: 6

Enter next number: -3

Enter next number: 4

Enter next number: 2

Enter next number: 11

Enter next number: 1

Enter next number: -9

Enter next number: end

The average of the sum of the squares is: 38.285714285714285

38.285714285714285
