Question
Find Variance within the groups, and variance between the groups, and the critical value
In Wisconsin, a study was conducted to see whether various artificial food
supplements differ for the rats. For 3 two-week periods, 3200 baits were placed
around garbage-storage areas: 800 consisted of plain flour; a second 800 had flour
mixed with artificial bean flavoring; a third 800 contained flour mixed with artificial
turkey flavoring; and the remaining 800 were flour mixed with artificial cheese
flavoring. The following table lists the percentage of each type of bait that was
eaten. Consider x=0.05; which statements are TRUE?
