A student reseаrcher wishes tо see if there reаlly аre differences in the cоffee sоld in coffee shops around Madison. They recruit 8 subjects for each of five groups (they could only afford to so many cups of coffee). One group drinks and rates Starbucks, a second group drinks coffee from Dunkin', a third group drinks coffee from Collectivo, a fourth from Moka, and a fifth group of participants drinks coffee from Grace Coffee Co. The researcher's results failed to produce a rejection of the null hypothesis. What statistical test did the researcher use and how could they have increased the power of their statistical test without resorting to recruiting more subjects? How exactly would this change increase their chances of rejecting the null hypothesis?
