Adding Noise to Data 3. (40 points) Write a script noisify.m where you first create a vector x that has 20 linearly spaced elements with values ranging from 1 to 20. Second, set a vectory equal to vi. Plot this sinusoidal curve. Finally, create a new vector, call it y2, and add random noise of amplitude between-0.05 and 0.05 (i.e. -0.05
