    2. Relevant equations

    3. The attempt at a solution

    I understand how to compute a Chi-squared test, but I'm a bit confused about the wording of parts a) and c). Could someone possibly simplify it for me?

    Thanks a lot.

    Google is your friend; search "chi squared test for independence".

    There are no parts a and c. Did you mean i and iii?
