    Think about a real-world situation that can be addressed using a one-way ANOVA. For this situation, clearly state the independent and dependent variables you would study; generate the null and alternative hypothesis; explain why you would need a post hoc analysis; and using realistic numbers for values of df, n, f-ratio, confidence intervals and post hoc results, report hypothetical results in a few sentences.

    This "real world" can be just about anything..can be simple.

    Please show work.
