Your best friend would like to attend dental school, and wants to study the effects of using the Oral-B 3D toothbrush. They randomly select 21 college students and asks them to use the toothbrush for 1 year. After that year, those 21 students have the following number of cavities: 0, 0, 1, 1, 0, 0, 0, 1, 0, 0, 0, 2, 0, 0, 1, 0, 0, 1, 4, 0, 1 Your friend claims to have more significant results than you because their group had, on average, fewer cavities. You claim that their results were not significant at the .05 level, even though their study had fewer cavities, on average. Complete a 6-step hypothesis test, using your friend's results, that the Oral-B 3D toothbrush combats tooth decay at the .05 level of significance.
