Question

Create two related hypotheses that you wish to study. The first hypothesis should be a one-population hypothesis like "Test the claim that the proportion of students who drive an alternative fuel or hybrid vehicle is greater than 10% with a 5% significance level." The second hypothesis should be a two-population hypothesis like "Test the claim that the proportion of students under age 21 who drive an alternative fuel or hybrid vehicle is greater than the proportion of students age 21 or over who drive an alternative fuel or hybrid vehicle with a 5% significance level."

Make five-question questionnaire that will provide your group with the data necessary to complete your hypothesis test. Two of the five questions are the required questions that provide the actual data to analyze. Three of the five questions are extra questions that are related to the topic designed to serve as distractions from the real questions. For example:

Do you drive an alternative fuel or hybrid vehicle? Yes or No. (circle one). (Required)

Are you Under Age 21 / Age 21 or Over (circle one). (Required)

Do you plan to buy an alternative fuel or hybrid vehicle? Yes or No. (circle one). (Extra)

How many miles per gallon does your current vehicle get? ___________ (Extra)

How often do you "fill your tank" now? __________ (Extra)

 

Answer 1

We need two data points in order to test our hypotheses:

Age of a person and the type of vehicle they drive

The questionnaire could be made as follows (starting from the basic question first)

1. Please mention your age (in years): ______ (Required)
2. How many days in a week do you travel to college by car? ___ (Extra)
3. Do you drive an alternative fuel or hybrid vehicle? (Required)
4. What are your average fuel expenses in a week? (Extra)
5. How much average (in miles/gallon) does your current vehicle get? (Extra)
