Question 3 (16 points) Three students were selected at random from each of three classes I'm teaching this semester. The table below shows the number of times each student was absent. Intro II 2 7 6 $1 = 2.65 SEL 8 1 3 82 = 3.61 Basic O BO 1 83 = 4.36 €1=5 2-4 3-3 L
21-522-4 23=3 !! Do this second: Calculate the Error sum of squares. Round to the nearest whole number. What is the alternative hypothesis testing whether there is a difference in mean absences for all students between these 3 sections? Do this first: Calculate the Groups sum of squares. Suppose the p-value turns out to be very low. What conclusion should we make? 1. 14₁ #1₂ #13 2. 84 3. 78 4. At least one population mean is different. 5. 41=2 μlz 6. Reject the null and conclude that there is strong statistical evidence that at least one population mean is different. 7.6 8. 3 9. Reject the null and conclude that we do NOT have strong statistical evidence that at least one population mean is different.
