Step 1 of 3

#complex data analysis examples #A machine that mass produces rubber gaskets can be set at one of three different #speeds: 100, 150 or 200 askes per minute. As part of a quality control study, the #machine was monitored several different times at each of the three speeds and the number #of defectives produced per hour was recorded. The data are provided in the table. Since #the number of...
