SNHU Applications of Two-Sample Test – Ripped Potato Assignment
Question Description
For your initial post, choose one of the following two prompts torespond to. Then in your two follow up posts, respond at least once ineach option. Use the discussion topic as a place to ask questions,speculate about answers, and share insights. Be sure to embed and citeyour references for any supporting images.
Write a confidence interval or hypothesis test problem using one ofthe options below. For whichever option you choose, gather appropriatedata and post your problem (without a solution) in the discussion topic.You may add another sample to the data that you gathered in your ModuleThree Discussion Topic post. Allow time for your classmates to posttheir solutions, and then respond to your own post with a solution forothers to check their work.
Option 1:
Think of a problem that you may be interested in that deals with acomparison of two population means. Propose either a confidence intervalor a hypothesis test question that compares these two means. Gatherappropriate data and post your problem (without a solution) in thediscussion topic. Later, respond to your own post with the solution forothers to check their work.
For example, you may want to know if the average weight of a rippledpotato chip is the same as the average weight of a non-rippled potatochip. You may weigh rippled regular potato chips from a large bag andfind weights of 1.7, 1.9, 2.4, 1.3, 1.7, and 2.0 grams. You may weighnon-rippled potato chips from another large bag and find weights of 1.8,1.6, 1.9, 1.9, and 1.4 grams. Assume a random sample was drawn.
Option 2:
Think of a problem that you may be interested in that deals with acomparison of two population proportions. Propose either a confidenceinterval or a hypothesis test question that compares these twoproportions. Gather appropriate data and post your problem (without asolution) in the discussion topic. Later, respond to your own post withyour own solution.
For example, you may believe that the proportion of adults inCalifornia who are vegetarians is more than the proportion of adults inNew Hampshire who are vegetarians. In two independent polls, you mayfind that 109 out of 380 California residents are vegetarians and 39 outof 205 New Hampshire residents are vegetarians.
For your response to a classmate (two responses required, one in eachoption), solve your classmate’s confidence interval or hypothesis testproblem, using a significance level not previously used Make sure thatyou use appropriate terminology and specify whether you are using theclassical method or the p-value method.
