Study Questions, Class 5

1. Thought question; True or false: The sample space for a discrete uniform random variable can be countably infinite.

False - the sum of the 1/k would be greater than 1.  

2. What is the size of the sample space (how many possible outcomes are there) for a Bernoulli trial?

2 outcomes, 0 or 1  

3. What is the parent distribution or underlying process for the Binomial distribution?

Bernoulli trials  

4. What is the parent distribution or underlying process for the Multinomial distribution?

"Multivariate" Bernoulli trials  

5. Why do the distributions above have parent distributions?

They are sampling distributions  

6.What is the difference between sampling schemes for the Binomial and Hypergeometric distributions?

Sampling with and without replacement
