In an effort to better manage his inventory levels, the owner of two steak and seafood restaurants, both located in the same city, hires a statistician
to conduct a statistical study. The owner is interested in whether the restaurant located on the south side sells more halibut fillets per night than the
restaurant located on the north side of the city.
The statistician selects a random sample of 30 nights that the southside restaurant is open. The mean number of halibut fillets sold per night at the
southside location is 15.3 with a sample standard deviation of 5.1. Likewise, the mean number of halibut fillets sold per night at the random sample of
31 nights that the northside restaurant is open is 16.8 with a sample standard deviation of 5.5.
Suppose you intend to conduct a hypothesis test on the difference in population means. In preparation, you call the sample of nights at the south
restaurant sample 1 and the sample of nights at the north restaurant sample 2. Organize the provided data by completing the following table:
