Unformatted text preview: randn to generate the signal. Type help randn to find how it works). Also using the Matlab code given with maximum plot time 5s and number of points to plot 400, print the plot and record the value of the mean and standard deviation produced by mean and std command. Calculate the 68% confidence interval of the true mean based on the recorded mean and standard deviation value. 3. Using Matlab, acquire and plot the histogram (20 bins) of the cosine wave with the following properties: signal frequency 15 Hz and amplitude 3 volts (6 Volts peak to peak), select the sampling frequency to be 1 Hz. Compare to the results obtained in the Pre-lab and explain why the histogram here does not have the shape expected for a sine wave histogram....
