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. Using the same excel sheet you submitted for Part 2, answer the following in the "Module 5" tab: ? For the average age, form a 95% confidence interval: o What distribution should be used? o What is the critical value? o What is the error bound? o What is the lower bound? o What is the upper bound? o How do we interpret the results, in context of our study? ? For the proportion of males, form a 95% confidence interval: o What distribution should be used? o What is the critical value? o What is the error bound? o What is the lower bound? o What is the upper bound? o How do we interpret the results, in context of our study?
