2. At a restaurant, a lemon odor was spread through the restaurant on one Saturday evening and no odor on
another Saturday evening. The number of minutes customers spent in the restaurant on both nights were
recorded. Since the Saturday evenings were comparable many ways, we will take our data as being from two
independent simple random samples. Here are the data:
Sample Mean
