Reaction to tear gas. The length of time Y (in minutes) required to generate a human reaction

Question:

Reaction to tear gas. The length of time Y (in minutes) required to generate a human reaction to tear gas formula A has a gamma distribution with α = 2 and β = 2. The distribution for formula B is also gamma, but with α = 1 and β = 4.

a. Find the mean length of time required to generate a human reaction to tear gas formula A. Find the mean for formula B.

b. Find the variances for both distributions.

c. Which tear gas has a higher probability of generating a human reaction in less than 1 minute?
