Once an individual has been infected with a certain disease, let
X represent the time (days) that elapses before the individual
becomes infectious. An article proposes a Weibull distribution with
α = 2.6, β = 1.1, and γ = 0.5. [Hint: The two-parameter Weibull
distribution can be generalized by introducing a third parameter γ,
called a threshold or location parameter: replace x in the equation
below, f(x; α, β) = α βα xα − 1e−(x/β)α x ≥ 0 0 x...

Once an individual has been infected with a certain disease, let
X represent the time (days) that elapses before the individual
becomes infectious. The article “The Probability of Containment for
Multitype Branching Process Models for Emerging Epidemics” (J. of
Applied Probability, 2011: 173-188) proposes a Weibull distribution
with alpha = 2.2, beta = 1.1, and gamma = 0.5
a. Calculate P(1 < X < 2).
b. Calculate P(X > 1.5).
c. What is the 90th percentile of the distribution?
