Question: 4. Evaluate the vector x given below in two different ways. First, use the MATLAB functions mean, median, and std. Then, compute the same value

4. Evaluate the vector x given below in two different ways. First, use the MATLAB functions mean, median, and std. Then, compute the same value without using these functions, i.e. evaluate the mathematical expressions directly, using elementary MATLAB functions and operations. The equations for mean and standard deviation are given below. What is the mathematical expression for median? x = [30, 40, 50, 66, 77, 99, 88, 99];
