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.

Please solve question 5.
Transcribed Image Text:4)- A Harris Corporation/University of Florida study was undertaken to determine whether a manufacturing process performed at a remote location can
be established locally. Test devices (pilots) were set up at both the old and new locations and voltage readings on the process were obtained. A 'good
process' was considered to be one with voltage readings of at least 9.2 volts (with larger readings being better than smaller readings). The table contains
voltage readings for 30 production runs at each location.
