Use a for loop please!

Create a function called avgSumOfSquares that expects one argument, a list of numbers. The function computes the average of the sum of the squares of all the values entered and then returns that value. If the list is empty, the function returns None. Do not use sum() or len(). Here are some examples of how your function should behave:

>>> avgSumOfSquares([1,2,3,4,5]) 11.0 >>> avgSumOfSquares([3.1, -7.8, 12, 5.5]) 61.175 >>> x = avgSumOfSquares([]) >>> print(x) None >>> avgSumOfSquares([]) >>>
