question 4

Essay

Suppose I want to know whether students in Santa Clara, U.C. Berkeley, and Stanford differ how much sleep they get per night, on average. I select random samples of 25 students from each school and measure how much they sleep. I calculate an ANOVA and this produces an SSb of 20 and an SSe of 200. Do the analysis to tell me whether the difference between the groups is statistically significant. Show your work and wrap words around your results. Be thorough.
