Ch. 6.1 (Probability Model For A Continuous RV)

Question 1

Discrete Probability Distribution

Answer 1

Takes on only some isolated values, usually integers (whole numbers) representing a count

Question 2

Continuous Probability Distribution

Answer 2

Can ideally assume any value in an interval

Question 3

Probability Density Function

Answer 3

Describes the distribution of probability for a continuous random variable

Requirements:

• total area under curve is 1
• the area is between A and B
• f(x) must be > or equal to all x

Question 4

Normal Distribution

Answer 4

Has a bell-shaped density

68. 3% within 1 SD of mean
69. 4% within 2 SD of mean
70. 7% within 3 SD of mean

Question 5

Standard Normal Distribution

Answer 5

A normal distribution with the parameters U = 0 and O = 1, denoted N(0,1)
