Question

Shoppers were asked about their regular grocery shopping locations. The table below shows the responses of the sampled shoppers. We are interested in determining if the proportions of females in the three categories are different from each other.

Gender	Grocery chain	Discount store	Membership warehouse	Total
Female	220	80	90	390
Male	80	70	60	210
Total	300	150	150	600

HINT: You are NOT to be run a full test here!! You need to use chi-square and comparison procedures!




d.	Compute the critical values (CVij) at the .10 level.
e.	Using pairwise comparisons, provide evidence showing which (if any) proportions are indeed different.
