Umbrella handles data

At an umbrella manufacturing facility, umbrella handles are measured and then removed from the assembly line if they don't meet specifications. A daily report indicates how many rejected handles were produced by each of three presses at the facility during each of three shifts. A quality engineer wants to determine whether press and shift are associated.

You can use this data to demonstrate Chi-Square Test for Association, Cross Tabulation and Chi-Square, Bar Chart of Values from a table, and other commands that analyze summary data in a two-way table.
