Problem 1. A car has gone out of control during a snowstorm and struck a tree. Construct a cause-andeffect diagram that identifies and outlines the possible causes of the accident. (4 points) Problem 2. The 24 factorial was used to investigate the effects of four factors on the filtration rate of a resin for a chemical process plant. The factors are A = temperature, B = pressure, C = mole ratio (concentration of chemical formaldehyde), D = stirring rate. This experiment was performed in a pilot plant and the dataset can be found in sheet Problem2 in Homework 4.xlsx. (a) Analyze this dataset of this factorial experiment with four-way interaction terms excluded. Identify what main effects, two-way interactions, and three-interactions are important? (2 points) (b) Analyze this dataset of this factorial experiment with both three-way and four-way interaction terms excluded. Identify what main effects and two-way interactions are important? (2 points) Problem 3. Propose a visual control that can be used to mitigate the spread of COVID-19 in Florida. (5 points) Problem 4. A high-voltage power supply should have a nominal output voltage of 350 V. A sample of four units is selected each day and tested for process-control purposes. The data (see sheet Problem4 in Homework 4.xlsx) give the difference between the observed reading on each unit and the nominal voltage times ten; that is, ???? = (observed voltage on unit ??  350)*10 (a) Set up ??? and ?? charts on this process. Is the process in statistical control? (2 points) (b) If specifications are at 350 V ±5 V, estimate ???? and ?????? , ???? and ?????? ? (2 points) (c) What can you say about process capability ???? ? (2 points) Problem 5. Consider potential causes of delayed mails or packages and perform a FMEA (Failure Modes and Effects Analysis) to help reduce the chance of delay delivery.
