    I can help you understand how to set up this hypothesis test for ammunition prices at two different stores.

    First off, you're interested in finding out if ammunition prices are lower at Gander Mountain than at Cabela's. So, you're talking about two different populations, but you want to sample prices for ammunition at each store, right?

    Since the manager at Gander Mountain believes his ammunition prices are lower, his null hypothesis is:
    H_o: mean difference (Cabela's-Gander Mountain)=0
    H_a: mean difference (Cabela's-Gander ...
