The null hypothesis of independence oi the two classications Aand B as shown on the 3x 3 contingency table was relected at the a = 0.10 level or significance. with x2 =8.612 and a prvalue of 0.0716. Use the 3x 3 contingency table to complete pans a through c below. 31 52 B; 37 60 40 63 52 as 31 35 28 a. Convert the responses to percentages by calculating the percentage of each B class total tailing into each Aclassmcation B 1 B2 3 A1 % % % A A2 % % % A3 % % % (Round to the nearest percent as needed.) Calculate the percentage of the total number oi responses that constitute each oitheA Classification totals.
