Problem 2: Twenty-five army inductees were given a blood test to determine their blood type. The data set is ABB AB O O OB AB B B BOA O A O O O AB AB A O BA The data are categorical, so discrete classes, one for each blood group, can be used. Step 1 Make a table showing class, frequency and percentage Step 2 Count the frequency of each category. (Use tally marks, if needed) Step 3 Find the percentage of values in each class by dividing the frequency of each class by the total number of values. Step 4 Find the totals for each column.
