Experiment, Pareto Chart

Question2: The test matrix and test data below show the results from a full factorial experiment on the effect of 3 variables, roughness (R), pipe diameter (D), and viscosity (V), on pressure drop in a pipe. Perform a Pareto analysis on the data to Determine the relative importance of the factors and plot in a Pareto chart. Test Matrix Run R D V 1 - - - 2 - - + 3 - + - 4 - + + 5 + - - 6 + - + 7 + + - 8 + + + Test Results Run Result 1 6.8 2 10.5 3 8.2 4 6.6 5 11.4 6 11.1 7 10.2 8 12.2

Histogram, steam and leaf diagram, box object plots

1. From the pressure data below, make a dot diagram. Mark the location of the mean and standard deviation. (You can use Excel or MATLAB to do this by plotting x-y data where all of the y points are 0. Minitab and R can also do this.) a. 25 28 29 35 37 37 42 44 45 47 49 56 87 91 2. Using the data from the strength of material tests below, find the mean, median, and standard deviation of the data set. Make the following types of plots. a. Stem-and-leaf diagram b. Histogram (bins of your choosing) c. Box plot See the attached file for data.

Breaking up Microsoft and the impact on competition

In the year 2000 a federal judge ordered that Microsoft be split into two separate companies because it had violated the antitrust laws of the United States. Some argue that the antitrust law are justified on grounds of the efficiency of competition. that is, breaking up a monopoly should result in a Pareto-efficient change. This cannot be so because breaking up Microsoft clearly makes its shareholders worse off. Do you agree or disagree? Explain your answer.

Explain Marginal Cost Curve

Explain: "That segment of a competitive firms marginal-cost curve that lies above its average-variable-cost curve constitutes the short-run supply curve for the firm." Illustrate graphically.

Discussion

During 2004, the national average gas price rose from $1.50 a gallon to $2.25 a gallon. The government has stated that the high price of gas will remain as it is. Discuss how this cost influences your decision to buy a new car. Based on your budget, would you buy the large car that gets 7 miles per gallon or the car that gets 25 miles per gallon? Explain. What is the difference between real GDP and nominal GDP? Does GDP accurately reflect our nation’s productivity? Explain your answer.
