A group of participants was surveyed and the information collected shown in the partially completed contingency table below regarding the site of skin cancer. Firstly, calculate the missing values. Melanoma Other Total Head U 43 X Trunk 52 V 98 Extremities 142 112 Y Total 229 W Z Now, using the completed contingency table, select the statements from the following list that are true. Note: a statement is true only if the value you calculated from the completed contingency table, when rounded to the same number of decimal places as in the statement, is the same as the value in the statement. 18.1% of skin cancers appear on the head 71.4% of skin cancers were melanomas or appeared on the head Given the skin cancer is something other than melanoma, the probability it is not on the extremities is 0.443 Of skin cancers appearing on the trunk, 46.9% are not melanomas
