2. Focus Problem “Personality Preference Types: Introvert or Extrovert?” Read page 205-206 in text book

3. 6.1 – Introduction to Random Variables and Probability Distributions Statistical Experiment is any process by which measurements are obtained. For example: Counting the number of A's on a test Measuring the heights of people in class Counting the number of defective cameras made at a factory Measuring the rainfall each day in inches

4. Random Variables Discrete can only be a finite number of values (countable) the number of A's on a test the number of defective cameras made at a factory number of oil wells drilled Continuous can take on any of the countless number of values on a line interval; can be decimals (measurable) the heights of people in class the rainfall each day in inches the volume of cylinders

6. Vocabulary A random variable has a probability distribution whether it is discrete or continuous Probability distribution: assignment of probabilities to the specific values OR to a range of values Features of the probability distribution of a discrete random variable: 1.has a probability assigned to each value of the random variable 2.Sum of all the assigned probabilities must be 1.
