Process Capability. R. Morris and E. Watson studied various aspects of process capability in the paper “Determining Process Capability in a Chemical Batch Process” (Quality Engineering, Vol. 10(2), pp. 389–396). In one part of the study, the researchers compared the variability in product of a particular piece of equipment to a known analytic capability to decide whether product consistency could be improved. The following data were obtained for 10 batches of product.
Construct a stem-and-leaf diagram for these data with
- a. one line per stem.
- b. two lines per stem.
- c. Which stem-and-leaf diagram do you find more useful? Why?

(a) Develop a scatter chart for these data with distance to work (in miles) as the independent variable and number of days absent as the dependent variable. Does a linear relationship appear reasonable?
Explain.
O Yes, there appears to be a positive linear relationship between distance to work (miles) and number of days absent.
O Yes, there appears to be a negative linear relationship between distance to work (miles) and number of days absent.
O No, there appears to be no noticeable linear relationship between distance to work (miles) and number of days absent.

Hair and Eye Color. In the article “Graphical Display of Two- Way Contingency Tables” (The American Statistician, Vol. 28, No. 1, pp. 9–12), R. Snee presented data on hair color and eye color among 592 students in an elementary statistics course at the University of Delaware. Raw data for that information are presented on the WeissStats site. Use the technology of your choice to do the following tasks, and interpret your results.
a. Obtain both a frequency distribution and a relative-frequency distribution for the hair-color data.
b. Get a pie chart of the hair-color data.
c. Determine a bar chart of the hair-color data.
d. Repeat parts (a)–(c) for the eye-color data.
