What is a cluster sample.

400
Model that finds the probability through Bernoulli trials, counting to the first success. 

What is a Geometric model.

400

Probability of not having success in a set number of trials, given probability of success. 

What is 1-geometcdf.

400

Accepting the null when it is invalid.

What is a type II error.

400
