Please provide detailed steps to solve. Thanks.

An epidemiologist found five cases of "big toe cancer" in the Yukon Territory. Because there were only a few cases, the epidemiologist decided to conduct a matched case-control study to determine whether shoe size larger than 9 is a risk factor for big toe cancer. Cases were individually matched to one control for daily activity, history of athlete's foot, and history of ingrown toenails. The following data were gathered:

Shoe size > 9

1 Yes No

3 No Yes
4 Yes Yes
