StatCrunch Assignment 3
In this assignment, you will use the
StatCrunch U data set that you
developed in Module 2 as part of the first
StatCrunch assignment.
As you did in StatCrunch Assignment 1B,
look at the items in the StatCrunch U
survey and develop a question regarding
population proportions that can be
answered using the survey data you
collected.
As a reminder, here are the items on the
survey:
Here are some possible questions. Feel free to pick one of those questions—but it would be
better for you to formulate a question of your own. For this assignment, you need a question
related to a single proportion (since our sample data is drawn from a single population) and
one that will require the use of a confidence interval and hypothesis test to answer.
NOTE: There is a sample StatCrunch Assignment 3 designed to give you an idea of how
to do this assignment. It uses a question related to the proportions of female and male
students at StatCrunch U. You cannot use that question on this assignment.
