The data in the following table compared women who viewed television violence with those who did not, in order to study the differences in physical abuse of the spouse. Use the output to test whether television violence and abusiveness are associated, using a significance level of 0.05. High TV Violence Low TV Violence Yes, Physical Abuse 12 30 No Physical Abuse 23 111 Chi-Square Test: High TV Violence, Low TV Violence Expected counts are printed below observed counts Chi-Square contributions are printed below expected counts High TV Low TV Violence violence Total Yes, ab 12 30 42 8.35 33.65 1.593 0.395 No 23 111 134 26.65 107.35 0.499 0.124 Total 35 141 176 Chi-Sq - 2.612, DF = 1, P-Value - 0.106 NOTE: in the boxed-in table, observed values are given first, then expected counts, then the chi-square contribution. From this data, answer the following: a) state the hypotheses for a chi-square test b) is this a test of independence or homogeneity? How do you know? a What conclusion can he drawn based on the give n-value and a significance. level.
