Using normpdf, normcdf and norminv for statistical qualitv control: A sticky wicket You are a quality control engincer in the manufacturing division of the World Wide Wicket Company (WWWco.) One of your plants has had a higher-than usual number of returns of defective wickets lately, due to the wickets having insufficient wickosity. Based on discussions with the plant managers, you have a suspicion that the wickets produced later in the week are the cause of the plant's problems. You want to determine statistically if this is the case You are going to make one long Matlab script for this assignment, adding to it at each step of the Figure 1: A WWWco wicket 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 vickosity measurement. 1. First, write a Matlab script to Load the data Use normplot to visually determine if the normal distribution is acceptable for each day'!s Determine the mcan and standard deviation of wickosity for each day, and output it neatly in * Using these sample means and standard deviations and the function normpdf, make a plot a table 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.
