MATLAB

For each day of the week, you pull 200 wickets off the production line and measure their wickosity. (The plant produces millions of wickets a day, so your sample of 200 does not affect plant production.) Demand for wickets is so high that the plant runs Monday through Saturday. The data file wickosity.mat contains these wickosity measurements. There are 6 columns in the data file, one for each day (except Sunday, when the plant is closed.) There are 200 rows in each column, and each row contains a wickosity measurement. First, write a Matlab script to Load the data Use normplot to visually determine if the normal distribution is acceptable for each days data. Determine the mean and standard deviation of wickosity for each day, and output it neatly in a table. Using these sample means and standard deviations and the function normpdf, make a plot of the estimated pdf for each day, all on the same graph. Please use subplot (with a 3 X 3 grid) to put these plots on the same figure. Please be sure to label and title the plots correctly. Your figure should look like this:
