Transcribed Image Text:Chicken diet and weight. In previous chapter, we compared the effects of two types of feed at a time. A
better analysis would first consider all feed types at once: casein, horsebean, linseed, meat meal, soybean,
and sunflower. The ANOVA output below can be used to test for differences between the average weights
of chicks on different diets.

Conduct a hypothesis test to determine if these data provide convincing evidence that the average weight
of chicks varies across some (or all) groups. Make sure to check relevant conditions. Figures and summary
statistics are shown below.
