Question

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 and some do not?

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?

Blank tables are provided for your calculations.

What are the null and alternative hypotheses for the chi square test of independence?

Calculate the expected frequencies for each “cell”

Using the steps shown in the lecture and in the text, calculate the chi square to investigate whether “passed certification” and “breed of dog” are independent of each other or not.

Compare your calculated chi square to the critical value of chi square per the table, using the correct degrees of freedom.
