Exercise 20

Note: Data sets for many problems in this chapter are available in the Excel workbook C06Data.xlsx on the Student Companion Site. Click on the appropriate worksheet tab as noted in the problem (e.g., Prob. 6-1) to access the data. In addition, the spreadsheet templates illustrated in the chapter are also available to aid in solving many of these problems.
The times for carrying out a blood test at River-creek Labs for 100 tests, found in the Prob. 6-12 , in the C06Data Excel workbook, were studied in order to better understand the process. Apply the Descriptive Statistics tool to compute summary statistics and explain the results. Also, construct a frequency distribution and histogram, for the data taken from set. From what type of distribution might you suspect the data are drawn?
