Short Answer

SCENARIO 11-12
A student team in a business statistics course designed an experiment to investigate whether the brand

Four brands of bubblegum were tested. A student chewed two pieces of a brand of gum and then blew

bubble at its biggest point. The following table gives the diameters of the bubbles (in inches) for the
16 observations.
