Student Major Categories Gender M Totals Male 7 Female 1 1 1 Totals 3 4 3 10 b. Construct contingency tables based on percentages of all 10 student responses, based on row percentages and based on column percentages. Complete the following contingency table based on total percentages. Student Major Categories Gender A M Totals Male 20.00 30.00 20.00 70.00 Female 10.00 10.00 10.00 30.00 Totals 30.00 40.00 30.00 100.00 (Round to two decimal places as needed.) Complete the following contingency table based on row percentages. Student Major Categories Gender A M Totals Male Female Totals (Round to two decimal places as needed.)
