Question

Do people feel hungrier after sampling a healthy food? The authors of a consumer research paper carried out a study to answer this question. They randomly assigned volunteers into one of three groups. The people in the first group were asked to taste a snack that was billed as a new health bar containing high levels of protein, vitamins, and fiber. The people in the second group were asked to taste the same snack but were told it was a tasty chocolate bar with a raspberry center. After tasting the snack, participants were asked to rate their hunger level on a scale from 1 (not at all hungry) to 7 (very hungry). The people in the third group were asked to rate their hunger but were not given a snack.

The data in the table are consistent with summary quantities given in the paper (although the sample sizes in the actual study were larger).

Find the test statistic and P-value. (Use technology. Round your test statistic to two decimal places and your P-value to three decimal places.)

F=P-value=

Treatment Group	Hunger Rating	Sample Mean	Sample Standard Deviation
Healthy	5	8	7	4	6	3	4	7	6	5.6	1.67
Tasty	4	1	5	2	6	2	5	3	4	3.6	1.67
No Snack	3	4	5	6	5	5	2	4	4	4.2	1.20
