Assignment 9 Write a generic class MyMathClass with at type parameter T where T is a numeric object (Integer, Double or any class that extends java.lang.number) Add a method standardDeviation (stdev) that takes an ArrayList of type T and returns a standard deviation as type double. Use a for each loop where appropriate. Hard code a couple of test arrays into your Demo file. You must use at least 2 different types such as Double and Integer Your call will be something like System.out.printIn("Standard Deviation 0-9 + MyMathClass.stdev (a)); Your class and method headers will be public class MyMathclass public static double stdev(ArrayList a) Research java' s Number class to see what useful method we are gaining access to Standard Deviation is the average amount of deviation from the average See /len.wikipedia The formula that must be implemented is Where the x with a bar over it is the average. The greek letter sigma stands for a summation. So you need to take each element in the array, subtract the average from it, square it and add this number to a total. After you take the total divide by the number of elements 1 and take the square root. Example If the Input is123456789 10 The average is 5s The result for the total would be: 1-5.5) (2-5.5) +2-5.5) (2-5.5) +(3-5.5) (3-5.5)+ Then divide this by N-1 or 9 and take the square root Excal gives: 3.3 as the standard daviation. +(105.5) 110-5.5
