B D E F G H M C Note: The goal of the project is to practice making a confidence interval for a mean and proportion with real data. Do not worry about failed assumptions tests and do not make corrections for small sample size. Use primary methods described in text and used on homework. 3 Age Gender Points 95% Confidence Interval for Average Age of Online College Students: 17 F 18 F Sample Mean: 38.17 21 M Sample St. Dev: 14.35 Note: Calculation cells should list 22 F 1 Sample Size: 24 the numbers and operations used to get your answers.
