Answer to Question 1

Gender and mode of transportation, both categorical.

Answer to Question 2

The breed selection does not appear to be independent of gender. Overall, 56 of the respondents were females, but females were over-represented among those who favored Golden Retrievers (64) and Dalmatians (62), yet a much lower percentage (47) among those who chose Labradors.
