Quiz: Ch 12 Quiz: ChiSquare Procedure O Question 2 of 10 This quiz: 10 point(s) possible This question: 1 point(s) possible Submit quiz The table to the right contains observed values and expected values in parentheses for two categorical variables, X and Y, where variable X has three categories and variable Y has two categories. Use the table to complete parts (a) and (b) below Click the icon to view the Chi-Square table of critical values. (a) Compute the value of the chi-square test statistic. = (Round to three decimal places as needed.) (b) Test the hypothesis that X and Y are independent at the (1 = 0.05 level of significance Ho: = and gy Y HI : gx*Ex or Wy H The Y category and X category are independent. HI The Y category and X category are dependent H The Y category and X category have equal proportions HI The proportions are not equal. H The Y category and X category are dependent HI The Y category and X category are independent. What range of P-values does the test statistic correspond to? The P-value is Should the null hypothesis be rejected7 No, do not reject Ho. There is sufficient evidence at the (1 = 0.05 level of significance to conclude that X and Y are dependent because the P-value < Yes, reject Ho There is not sufficient evidence at the 0.05 level of significance to conclude that X and Y are dependent because the P-value > a. Yes, reject Ho There is not sufficient evidence at the 0.05 level of significance to conclude that X and Y are dependent because the P-value < a. No, do not reject Ho. There is not sufficient evidence at the a = 0.06 level of significance to conclude that X and Y are dependent because the P-value > cr. (3327) 4389 16 20 (13.73) 18.11 (4884 16 o. 16
