Edit question Suppose in an effort to manage his inventorylevels better, the owner of two steak and seafood restaurants, bothlocated in the same city, hires a statistician to conduct astatistical study. The owner is interested in whether therestaurant located on the south side sells more halibut fillets pernight than the restaurant located on the north side of the city.The statistician selects a random sample of 102 nights that thesouth-side restaurant is open. The mean number of halibut filletssold per night at the south-side location is 15.3 with a samplestandard deviation of 0.4. Likewise, the mean number of halibutfillets sold per night at the random sample of 83 nights that thenorth-side restaurant is open is 16.8 with a sample standarddeviation of 5.5.
Suppose you intend to conduct a hypothesis test on thedifference in population means. In preparation, you identify thesample of nights at the south restaurant as sample 1 and the sampleof nights at the north restaurant as sample 2. Organize theprovided data by completing the following table:
Sample 1 Sample 2 N1 = N2 = ?1 = ?2 = X??1 = X??2 = ?1 = ?2 = s1= s2 = The difference in sample means for sample 1 and sample 2 is. The estimate of the standard deviation of the samplingdistribution of the differences in sample means, s(X???X??) , is .Now, you know all that you need to know to answer the questionabout whether the restaurant located on the south side sells morehalibut fillets per night than the restaurant located on the northside of the city.
