1.2 11. A researcher is interested in differences in travel behavior for residents living in four different regions. From a sample of size 48 (12 in each region), she finds that the mean commuting distance is 5.2 miles, and that the standard deviation is 3.2 miles. What is the total sum of squares? Suppose that the standard deviations for each of the four regions are 2.8, 2.9, 3.3, and 3.4. What is the within sum of squares? Fill in the table: Sum of squares df Mean square Between Within Total LL.
