In the general population, patients who are recovering from bronchial pneumonia normally take a mean (average) of 4.75 days to leave the hospital, with a population standard deviation of 1.82 days. Medical personnel at a hospital are trying a new medication that is designed to ease breathing during recovery. What is not currently known is whether the new medication will impact duration of hospital stay. The first sample of 25 patients (n=25) to whom this medication was administered were released from the hospital in a mean (average) of 2.60 days. Based on this result, should the hospital conclude that there is a significant difference in duration of hospital stay because of the new medication?

Calculate the 99% confidence interval. Which 2 values will be required to complete the following equation for the confidence interval?

2.1416 < µ < 4.2584

1.7319 < µ < 3.4281

1.6609 < µ < 3.5391

1.8068 < µ < 4.5932

0 < µ < 1.96

    What are some of the important considerations for Heartland Shoes in each phase? In Phase 2 include a Context diagram for Heartland which will model how the inventory system will work.

    1. Heartland Shoes is a family owned retail shoe store. They have one store and their competitive advantage is providing a good selection and good old-fashioned customer service. Gross revenue for the store is roughly $250,000 annually. Heartland Shoes has struggled with the problem of poor inventory control. It takes a while to find shoes in the back room for customers (if they are even there). They do not have easily accessible sales records. They struggle to know which shoes to restock. Employees must go to the back room and physically count inventory. They have no computer system and keep information on purchase orders, received reports and invoices in metal file cabinets. Consider the five phases of an SDLC.
