# Math 201: Statistics

(25 points) Part 3  Confidence Intervals (Week 5): Based on the class sample, you will create a 95% confidence interval for the mean age and the proportion of males in the population of all online college students.
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 as last week, answer the following in the week 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?

Graph on first tab Q1 should be the average of 19 and 22
Your graphs should have titles that relate to the data…like Ages of online students.
