Problem 75E

Gaussians An important function in statistics is the Gaussian (or normal distribution, or bell-shaped curve), .

a. Graph the Gaussian for a =0.5, 1, and 2.

b. Given that , compute the area under the curves in part (a).

c. Complete the square to evaluate , where a > 0, b, and c are real numbers.

Answer;

     Step-1;

 Given gaussian function is; f(x) = .

     

            Now , we have to sketch the  graph the Gaussian for a = 0.5, 1, and 2. 

       

          If a = 0.5 , then  the  graph of  the Gaussian function y=  is;

                                     

   If a = 1 , then  the  graph of  the Gaussian function y=  is ;

                                           

 

 If a = 2 , then  the  graph of  the Gaussian function y=  is ;

                                                     

Step-2;

         b)     Given that  dx =  

           Now , we have to find out the area under the curves in part (a).

                       We know that  dx =   means area under the curve between , and x -axis is .

      Therefore, the area under the curve between , and x -axis is;

                                             dx = .Since a = 0.5

         Thus ,  the area under the curve between , and x -axis is;

                                             dx = .Since a = 1

       Therefore ,  the area under the curve between , and x -axis is;

                                             dx =
