Using the information from Section 1.2.3, what would be the number of suspected pairs if the following changes were made to the data (and all other numbers remained as they were in that section)?
(a) The number of days of observation was raised to 2000.
(b) The number of people observed was raised to 2 billion (and there were therefore 200,000 hotels).
(c) We only reported a pair as suspect if they were at the same hotel at the same time on three different days.
