In 1996 the Food and Drug Administration approved the use of the fake fat Olestra for use as a food additive. Olestra is chemically similar to dietary fat, but it cannot be easily digested by humans. When added to foods like potato chips, it preserved the taste and texture but reduced the calories, so it became a fat-replacement additive much the way Nutrasweet or Sucralose replaces sugar. Soon after it's release however, reports started surfacing claiming consumption of Olestra-containing foods caused intestinal distress and cramping. To evaluate this claim, researchers asked 1100 individuals aged between 13 and 38 to eat potato chips while they watched a movie. Each participant received an unmarked bag that contained 370g of chips. Half of the participants received Olestra chips, the other half received chips made with normal fat (vegetable oil). A few days after the movie, the participants were contacted and asked about any-post movie cramping. 15.8% of the Olestra chip eating group reported cramps, compared to 17.6% of the normal chip eating group. Which of the following would be a plausible hypothesis for this study?
Consumption of Olestra causes intestinal cramps
