4. Commercials for chewing gum make claims about how long the flavor will last. In fact, some commercials claim that the flavor lasts too long, which negatively impacts sales and profits. A researcher decided to test these claims. He recruits 5 participants. Each participant is asked to chew a different piece of gum each day for 4 days. After 20 minutes of chewing the gum, participants are asked to rate the flavor on a scale of 1 (not intense) to 9 (very intense). The average score for the four brands of chewing gum are shown in the table below, along with an incomplete summary table. Does the flavor of any of the brands of chewing gum last longer than others? Set a = .05. Brand A M = 4 a. What is H₁? Brand B M = 8 b. Set criterion for making a decision about Ho: c. Complete the summary table below: Brand C M = 5 Brand D M = 3
