Term
|
Definition
| 2 possible outcomes, probability of success is constant, trials are independent |
|
|
Term
| Geometric probability model |
|
Definition
| a Geometric model is appropriate for a random variable that counts the number of Bernoulli trials until the first success |
|
|
Term
| Binomial probability model |
|
Definition
| a Binomial model is appropriate for a random variable that counts the number of successes in a fixed number of Bernoulli trials |
|
|
Term
|
Definition
| when sampling without replacement, trials are not independent; it's still okay to proceed as long as the sample is smaller than 10% of the population |
|
|
Term
| Success/Failure Condition |
|
Definition
| for a Normal model to be a good approximation of a Binomial model, we must expect at least 10 successes and 10 failures |
