3 The number of defective items produced on an assembly line per day is counted for a random sample of 20 days. The results are in the following table: 21 16 99 11 10 13 12 11 25 10 14 26 9 11 12 12 19 11 9 a) Draw a Dotplot. Be sure to label and scale appropriately. b) Based on the Dotplot, is it reasonable to treat this sample as if it comes from an approximately normal population? Briefly explain. c) Draw a Boxplot. Be sure to label and scale appropriately.
