6.1 Day 1Discrete and Continuous Random Variables

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?
