![Question 30
A randomly selected realtor's monthly commission (in thousands) can be estimated by a random variable
that follows F-distribution with parameters (14,4). Let X be the monthly commission of a randomly
selected realtor.
1. Describe the distribution of X:
P(X<13.1)=0.99
X<7.1
P(X<7.9)
P(X<13.1)=0.99
2. Use the random variable notation to express symbolically each of the following:
X<7.1
P(X<7.9)
P(X<13.1)=0.99
X<7.1
P(X<7.9)
