     Conduct   an Analysis of Variance for the following equation: A psychologist at a   private hospital was asked to determine whether there was any clear   difference in length of stay of patients with different categories of   diagnosis. Looking at the last four patients in each of the three major   categories, the results (in terms of weeks of stay) were as follows:    Diagnosis Category Affective   Disorders Cognitive Disorders Drug-Related Conditions    7 12 8    6 8 10    5 9 12    6 11 10    Using the α = .05 level and   the 5 steps of hypothesis testing, is there a significant difference in the   length of stay among diagnosis categories? Explain your answer.
