Q1:

There are 209 dogs who participate in a training to become service dogs.

There are four breeds of dogs.

Some dogs pass the certification test (shown in top row below) and some do not (shown in second row).

Chi square question:

Is there an association between breed of dog and passing the test? Or, are breed and passing the test independent of each other?
