A coffee machine dispenses coffee into paper cups. You’re supposed to get 10 ounces of coffee, but the amount varies slightly from cup to cup. Here are the amounts measured in a random sample of 20 cups. Find a 95% confidence interval based off of these sample data to capture the true mean. Is the true mean actually captured in your interval?. Section 8.1. Confidence Intervals: The Basics. After this section, you should be able to…. INTERPRET a confidence level. INTERPRET a confidence interval in context. DESCRIBE how a confidence interval gives a range of plausible values for the parameter. Day 19. A new example, with less information:. Now I want to know about the average height of three year old apple trees. A random sample of 60 trees gave us a standard deviation of 2.8 inches (so we’ll assume .

Week 10 Chapter 16. Confidence Intervals for Proportions 1 Point and Interval Estimation A point estimate, for example, estimated mean or estimated proportion, is a single number that is the best value for the parameter (e.g., population mean, or population proportion).
