1. Construct a relative frequency histogram for the voltage readings of the old process. 2. Construct a stem-and-leaf display for the voltage readings of the old process. Which of the two graphs in parts an and b is more informative? 3. Construct a frequency histogram for the voltage readings of the new process. 4. Compare the two graphs in parts a and c. (You may want to draw the two histograms on the same graph.) Does it appear that the manufacturing process can be established locally (i.e., is the new process as good as or better than the old)? 5)- Find and interpret the sample mean and median for each of the voltage readings data sets in Problem 4. Which is the preferred measure of center tendency? Explain.
