    1. Make a boxplot to compare weight across the different types ofDiet. Based on the boxplot, describe any differences (or lack ofdifferences) you see.
    2. Run an ANOVA to compare weight across the different types ofDiet. Is there a significant difference in means?
    3. Regardless of your answer to part b, using Tukey’s HSDapproach, which pair or pairs of Diet have significantly differentmeans?
    4. Check the assumptions of the ANOVA: Do the variances looksimilar across groups? And do the residuals look like they couldhave come from a Normal Distribution?
