Question 2: The U.S. Department of the Interior releases figures on mineral production. The following are the 15 leading states in nonfuel mineral production in the United States in 2008:

  • Arizona: 8.95 billion dollars
  • Nevada: 6.48 billion dollars

a) Using the appropriate tool in the data analysis toolpak in Excel, calculate the descriptive statistics. Include the summary statistics table in your report.

b) Briefly define the meaning of each of the metrics in the summary report you get.

c) Comment on all of the figures in the report. What do you learn from these metrics? What are they telling you about this data set? Is it symmetrical, flat, or skewed? Does it have outliers?

Question 3: Suppose Procter & Gamble sells 20 million bars of soap per week, but the demand is not constant, and production management would like to get a better handle on how sales are distributed over the year. Let the following sales figures, given in units of million bars, represent weekly sales over one year (in no particular order): 17.1, 14.4, 12.2, 11.9, 26.4, 10.9, 12.8, 13.4, 21.5, 39.8, 30.4, 20.7, 25.8, 20.3, 21.3, 26.6, 13.8, 22.5, 26.4, 23.6, 21.4, 32.1, 23.4, 26.9, 20.4, 23.1, 26.1, 15.4, 14.8, 24.5, 20.3, 21.4, 26.7, 24.8.

a) Construct a histogram chart to represent the data using the appropriate tool from the data analysis tool pack. Specify your own bin ranges (e.g., multiples of 5 from 10 to 40) instead of relying on Excel's default.

b) Create a brief analysis of the graph. What do you see in the graph that might be helpful to the production and sales teams?
