For this assignment, you need to come up with ONE one proportion claim and analyze your claims in Minitab using the Project 2 Class Data and then do any needed followup. The following video provides a walkthrough of this assignment and some helpful hints!
Assignment Directions
For this assignment work through the information below stepbystep to do a one proportion hypothesis test in Minitab. You can just provide the answers for each step (on your paper you submit) OR you can write this up in full sentence/paragraph format, which is what you'll need to do for the Project 2 paper (recommended).
Step 1: Write your Claim
The Step 1 directions will help you write your claim correctly, but you only need to provide your response to #5 (your claim) for Step 1 on your assignment. If you'd like to include the information from 15 you can, but it is not needed. Just the wording of your claim is needed.
 Pick one of the following questions that you'd like to analyze using Minitab:
 Question 1: Did you grow up in a household with guns? [Yes, No]
 Question 2: Do you support allowing concealed carry in more places? [Yes, No]
 Pick one of the answer options from the question you picked in #1.
 Example: If you picked Q1, you would then pick either the answer option Yes or No.
 What is the percent from the Pew article for the answer option you picked for #2? For example, if you picked Q1 and yes, the percent would be 48%.
 Q1: Grow Up  Yes = 48%; No = 52%
 Q2: Conceal Carry  Yes = 45%; No = 55%
 Do you think the percentage from Pew (from #3) is higher, lower, or equal to the data we collected?
 Example: I think our responses to Q1 and Yes, is higher than the results from Pew.
 This is your besteducated GUESS, do not look at the data and then make your guess.
 Take the information from #14 to write your claim.
 Example: For Q1 and the yes answer option Pew found 48%. Claim  The percentage of people in our survey who grew up in a household with guns is higher than 48%.
 Claims must be based on the percentage found from the Pew study. Do not use the percentages we found in our study!
 Claims have to be written in an appropriate manner for a one proportion test, so review the course resources to see how to write your claim correctly.
Step 2: Information about your Claim & the Statistical Test you are Using
Provide your answer to #1#2 below on your assignment.
 Is your claim the null or alternative claim?
 State specifically why a oneproportion test is appropriate to use for this claim. So why would you analyze your data with a one proportion test instead of a different statistical test? [Hint, go back to what a one proportion test is used to determine from the class notes.]
Step 3: Analyze the Data using Minitab
Using the Project 2 Data, provide your answer to #1#2 on your assignment.
 Use Minitab to analyze your claim and copy (as a PNG image) ALL of the Minitab output into your assignment except the graph (95% Upper bound for the Proportion).
 Make sure to review the lecture and One Proportion Minitab information on how to analyze one proportion tests.
 Provide the appropriate statistics/information from the Minitab output that allows you to make a decision about your claim. This information must be typed out on your assignment.

Step 4: Provide a Conclusion & Explanation of your Results
Provide your answer to 12 on your assignment.
 Provide a conclusion that answers the original question/claim. Use this exact format:
 There [IS, IS NOT] enough evidence to [Support, Reject] the claim that.... [Restate your claim from Step 1 above].
 Provide a realworld explanation for these results. What do the results of your Minitab analysis actually mean? Things to think about when you try to answer this question: Is our class data different than the results of the PEW survey/article? If so, then explain HOW our results differ from Pew. If our results don't differ statistically, then talk about what the data does show.
Step 5: Is any followup testing needed?
 Review your results from Step 4 and determine if any followup testing is needed. Explain why or why not.
 If followup is needed, then go ahead and do the followup and include the results. Information to include if followup is needed:
 Followup claim you are testing.
 Minitab output
 Minitab results  There [IS, IS NOT] enough evidence to [REJECT, SUPPORT] the claim that... restate followup claim.
 Realworld explanation of results.
Once you are finished, submit the needed information for all five steps to this assignment!
