a) When does the number of Actives reach its peak? How many people are infected at that time? b) Initially, how many Potentials are there? How many days does it take to cut the Potential population in half? c) How many days does it take the Rejected population to reach 500,000? How many people have rejected the product by day 60? d) On what day is the size of the Active population increasing most rapidly? When is it decreasing most rapidly? How can you tell? e) How many people became Active at some time during the first 30 days? (Note that this is not the same as the number of Active people on day 301) Explain how you found this information.
