Implement Method Java Include Test Api Implement Upvote Best Answer Computes Standard Gaus Q43810752

How do I implement this method in java. I will include, both thetest and the api to implement. Will upvote the best answer

Computes the standard Gaussian distribution probability densityfunction (see
       * the lab document for the actualformula) with scale parameter.
       *
       * @param x
      *           a value
       * @param sigma
      *           scaleparameter         
       * @return the standard Rayleighdistribution probability density function
      *         evaluated atx
       */
   public static double gaussian(double x, int sigma){
      
      
   }

Test Case:

    public void test03_gaussian() {
       final double[] x = { -3.0, -1.0, 0,1.0, 3.0};
       final double[] exp ={0,    0.1468,   0.3989,  0.1468,   0 };
       int sigma=1;
       for (int i = 0; i < x.length;i++) {
           String error =String.format(“normal(%s) failedn”, x[i]);
          assertEquals(error, exp[i], lab0.gaussian(x[i], sigma),1e-1);
   }
   }
