A researcher is interested in evaluating the association between age and the proportion of subjects consuming different brands of soft drinks. Consider the table below, formed by cross-classifying age groups and brands. DATA: Cola 1 Cola 2 Cola 3 Under Age 15 Questions: 170 216 328 Age 15-25 124 145 232 Age 25-35 228 232 336 The researcher wants to evaluate the following hypothesis: Ho: There is no association between the two factors (i.e. there is no difference in the proportion of people consuming different brands of soft drinks). Against HA: There is an association between the two factors. The calculated "x²" statistics for this particular data set was found to be: 5.62 1. What is the critical value of "x²" using an alpha=0.1 (round to the nearest tenth) Blank 1 2. Given the "x²" calculated and the critical value of "x²" indicate if you are going to reject or fail to reject the null hypothesis using an alpha=0.1 Blank 2
