Define X; to be the incubation period of Covid-19 in patient i. Assume that X; has an approximately normal distribution with mean 5.1. (The article says the median is 5.1, and since we're assuming a normal distribution, which is symmetric, the mean also is 5.1). The article says that 0.975 of people develop symptoms within 11.5 days of exposure. In other words, P(X; < 11.5) = 0.975. Calculate the standard deviation of the distribution of X Four decimals 3.2

Question
Incubation period for Covid-19
At the end of the pdf of this quiz (posted in the topic module) is a Wall Street Journal
article about the incubation period of the coronavirus (how long it takes symptoms to
appear after the person is exposed and contracts the virus). The article gives the median
and a couple of probabilities. We'll make the additional assumption that the incubation
period is approximately normally distributed in the population of people who contract the
virus.
This is the first of 2 questions in this set.
