Which three distributions are named for study in these chapters?
AUniform, exponential, normal
BBinomial, Poisson, geometric
CChi-square, F and t only
DBernoulli, gamma and beta
Answer & Solution
Correct answer: A. Uniform, exponential, normal
1. Continuous distributions are introduced in a set order.
2. Chapter 5 and the next one study three named distributions.
3. They are the uniform distribution, the exponential distribution and the normal distribution.
4. Discrete families such as the binomial are treated separately.
