Chapter 5

Question 1

Binomial Experiment

Answer 1

An experiment having the four properties stated at the beginning of Section 5.5.

Question 2

Binomial Probability Distribution

Answer 2

A probability distribution involving two random variables. A discrete bivariate probability distribution provides a probability for each pair of values that may occur for the two random variables.

Question 3

Binomial Probability Function

Answer 3

The function used to compute binomial probabilities.

Question 4

Bivariate Probability Distribution

Answer 4

A probability distribution involving two random variables. A discrete bivariate probability distribution provides a probability for each pair of values that may occur for the two random variables.

Question 5

Continuous Random Variable

Answer 5

A random variable that may assume any numerical value in an interval or collection of intervals.

Question 6

Discrete Random Variable

Answer 6

A random variable that may assume either a finite number of values or an infinite sequence of values.

Question 7

Discrete uniform probability distribution

Answer 7

A probability distribution for which each possible value of the random variable has the same probability.

Question 8

Empirical Discrete Distribution

Answer 8

A discrete probability distribution for which the relative frequency method is used to assign the probabilities.

Question 9

Expected Value

Answer 9

A measure of the central location, or mean, of a random variable.

Question 10

Hypergeometric probability distribution

Answer 10

A probability distribution showing the probability of x successes in n trials from a population with r successes and N − r failures.

Question 11

Hypergeometric probability function

Answer 11

The function used to compute hypergeometric probabilities.

Question 12

Poisson probability distribution

Answer 12

A probability distribution showing the probability of x occurrences of an event over a specified interval of time or space.

Question 13

Poisson probability function

Answer 13

The function used to compute Poisson probabilities.

Question 14

Probability Distribution

Answer 14

A description of how the probabilities are distributed over the values of the random variable.

Question 15

Probability Function

Answer 15

A function, denoted by f(x), that provides the probability that x assumes a particular value for a discrete random variable.

Question 16

Random Variable

Answer 16

A numerical description of the outcome of an experiment.

Question 17

Standard Deviation

Answer 17

The positive square root of the variance.

Question 18

Variance

Answer 18

A measure of the variability, or dispersion, of a random variable.
