• Implement the functions which have been defined (Exercise 5). I expect this to be done with actual code, not by using the built-in python methods/functions. While you are not allowed to use the built-in python functions and methods for processing lists (sort, max, min, etc), you are allowed to import the math library for the standard deviation function.
• Add a function which returns five integers corresponding to the number of scores in each range: the 90s, the 80s, the 70s, the 60s, and below 60
