Feeding the Future is a company that produces healthy foods for children. They have recently developed a new product called Krunchy Kale Krisps and they want to test how popular these delicious treats will be with children. The researchers think that the age of the child may have an affect on how much they will enjoy the healthy treats. They run an ANOVA to test this. They separate age by 4-6, 7-9, and 10 and over. They then assess how much the children in their sample report that they like the treats on a scale of 1-10. The researchers at Feeding Our Future find that children 4-6 report a mean degree of enjoyment of 3.2, the children aged 7-9 report an enjoyment mean of 3.4, and the children aged 10 and over report a mean of 1.6. If the results of an ANOVA indicate that p=.001 at an alpha of .05, we can conclude that:

the groups are all significantly different.

the children aged 7-9 like Krunchy Kale Krispies more than children of other ages did.

there is a significant difference between at least two of the groups.

we don't have enough information yet to conclude anything.
