Suppose you are interested in the relationship between a person's age and the amount of community activism in which he or she is involved. You randomly select 12 people from each of three different age categories and ask each person to estimate the number of hours spent engaged in any type of community activism or volunteer activity during the past 30 days (X¡). You obtain the following data summary from your investigation: Age Group 18-30 31-50 Over 50 EX; = 65 Σχ339 Σχ? 367ΣΧ? = 289 ΣΧ 63 ΣΧ57 In the following questions you will practice using the formulas from the text to calculate the main components of an ANOVA. According to the summary data table, the total sample size is N = and the overall mean is X = The three category means are X1 v,X2 = and X3 Calculate the sum of squares total (SST), the sum of squares between (SSB), and the sum of squares within (SSW) this data set. SST = SSB = SSW =

Your younger brother, a fourth form practical geography student wishes to test whether there could be some relationship between annual visits to a local market by all residents surrounding that market. After a well-designed field study he obtains the following figures: Number of visits per year 21 13 19 18 17 17 14 20 10 11 Residence distance from market (KM) 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 From the information above, what is the dependent variable and what is the explanatory variable? Using (i) above, obtain the regression equation of Yi on Xi. Hence, estimate the residence distance from the market (in KM) if the number of visits are 16 visits Sketch your results in (ii) above. What conclusion can you draw from your sketch?
