Create a program to calculate simple descriptive statistics on numbers stored in an array (you can require that a fixed number of numbers be entered e.g. always calculate on 10 numbers).

• Create a form that allows the user to enter a number and a button that when clicked will update three labels: Sum, Average, and maximum of all numbers entered.
• Store the numbers in an array.
• Create specific methods to calculate Sum, Average, and Maximum for the numbers stored in the array.

Concepts: Arrays. Loops. Calculations. Methods.
