Using Matlab, and fprintf must be used, not disp()

Calculate the standard deviation, the only build in function that you can use is SUM. The formula for computing standard deviation, s, within a data set is: s =plusminus Squareroot sigma_i = 1^n (x_i - x)^2 where, n is the number of points, x_i are the individual points, and x is the average In the script file, perform the following tasks: Read in the power data from Watts.dat (to do this use command: load('Watts.dat') Make sure Watts.dat file is in the same folder that you are working in. The command will create a vector Watts with the values in that file. Calculate the average of the home power requirements. Calculate the standard deviation of the home power requirements. Print to the command window the average power, the standard deviation, and the amount of power that satisfies the requirement of being one standard deviation above the average, properly labeled and with proper units
