Question: Create a 3 2 contingency table with row totals of 25, 30, and 25 and column totals of 30 and 50. How many table

Create a 3 × 2 contingency table with row totals of 25, 30, and 25 and column totals of 30 and 50. How many table cell counts are truly free (i. e., what is the smallest number of table cell counts that, when filled in, will completely specify the rest of the cells)? Describe how the formula (number of rows – 1) × (number of columns – 1) relates to the number of free cells in a two- way contingency table of any size. It may be helpful to create a 3 × 3 table or a 3 × 4 table to convince yourself that this rule continues to hold.
