One-way ANOVA Instructions

You’ve been asked to see whether there is a significant difference in rates of dehydration upon admission for patients 75 years and older (column HS) for Alabama, Georgia, and Louisiana.  State your null and alternative hypotheses. Next, calculate the Sum of squares, squares within groups, squares between groups, and F statistic by hand. Now, use the ANOVA function within Excel for the calculation. What does the value of the F statistic tell you? Do you accept or reject the null hypothesis?

You will submit an Excel sheet and a Word document.
