Question

Diet Thirteen overweight women volunteered for a study to
determine whether eating specially prepared crackers before
a meal could help them lose weight. The subjects were
randomly assigned to eat crackers with different types of
fiber (bran fiber, gum fiber, both, and a control cracker).

Unfortunately, some of the women developed uncomfort-
able bloating and upset stomachs. Researchers suspectedthat some of the crackers might be at fault. The contingency
table of “Cracker” versus “Bloat” shows the relationship
between the four different types of crackers and the reported
bloating. The study was paid for by the manufacturers of the
gum fiber. What would you recommend to them about the
prospects for marketing their new diet cracker?

Bloat
Little/None Moderate/Severe

Cracker
Bran 11 2
Gum 4 9
Combo 7 6
Control 8 4
