Question

Imagine a student decides to compare how long a gum's flavor will last using 4 different gums and 5 participants. Each participant was asked to chew a different gum each day for 4 days, such that at the end of the 4 days, each participant had chewed all four types of gum. The order of the gums was randomly determined for each participant. After 2 hours of chewing, participants recorded the intensity of flavor from 1 (not intense) to 9 (very intense). Here are some hypothetical data: Person 1 Person 2 Person 3 Person 4 Person 5 Gum 1 4 6 3 4 4 Gum 2 8 Gum 3 5 4 Gum4 2 2 3 2 What is the MSbetween for this scenario? 0.576 O 938 23.9 O31.267 MacBook Air F7 F8 19
