  1. 6.1 Day 1 Discrete and Continuous Random Variables

  2. Bottled Water Problem • 13 out of 21 students correctly identified the bottled water. How many correct identifications would you need to see to be convinced that the students in your class aren’t just guessing? With your partners, design and carry out a simulation to answer this question. What do you conclude about the class’s ability to distinguish tap water from bottle water?

  3. Learning Targets • I can use a probability distribution to answer questions about possible values of a random variable. • I can calculate the mean of a discrete random variable. • I can interpret the mean of a random variable

  4. Random Variable and Probability Distribution • A random variable takes numerical values that describe the outcomes of some chance process. The probability distribution of a random variable gives its possible value and their probabilities.

  5. Discrete Random Variables

  6. NHL Goals
