Question

In the study with monkeys by Dawn Dudley’s team, most monkeys infected with Zika cleared the virus within 10 days. In one pregnant monkey, however, the virus lasted 57 days. On a percentage basis, how much longer was that than the average? Imagine that the virus lasted 34 days in another animal. How much longer was that than the average (on a percentage basis)? How much shorter was that (on a percentage basis) than the infection that lasted longest? Show your work.
