Problem 3. (10 points) Family transportation costs are usually higher than most people believe. Eighteen randomly selected families in three major cities are asked to use their records to estimate a monthly figure for transportation cost. Use the data obtained and ANOVA to test whether there is a significant difference in monthly transportation costs for families living in these cities. Use a = 0.05. Edmonton Toronto Vancouver 650 250 350 180 525 700 550 300 950 600 175 780 675 500 600 540 150 675 (a) Specify the appropriate statistical hypotheses. O A. Ho : At least one of the means is different from the others. HA : The means are the same B. Ho : The three population means are the same. HA : All three means are different from the others. O C. Ho : The three population means are the same. HA : At least one of the means is different from the others. (b) Complete the following one-way ANOVA table (You can either use R studio for calculation or by hand). Source Degrees of Freedom Sum of Squares Mean Square F P-value City Error Total (e) Do the data suggest that there is a significant overall difference of transportation costs between these three major cities? ? v
