Choose one of the following two prompts to respond to. In your two follow up posts, respond at least once to each prompt option. Use the discussion topic as a place to ask questions, speculate about answers, and share insights. Be sure to embed and cite your references for any supporting images.

Option 1:

Think of a problem that you may be interested in that deals with a comparison of two population means. Propose either a confidence interval or a hypothesis test question that compares these two means. Gather appropriate data and post your problem (without a solution) in the discussion topic. Once your initial post is complete, respond to your own post with the solution for others to check their work.

Option 2:

Think of a problem that you may be interested in that deals with a comparison of two population proportions. Propose either a confidence interval or a hypothesis test question that compares these two proportions. Gather appropriate data and post your problem (without a solution) in the discussion topic. Once your initial post is complete, respond to your own post with the solution for others to check their work.

For your response to a classmate (two responses required):

Pick two classmates to complete both of their sample test problems using a significance level not previously used for that specific classmate’s problem. Include the null and alternative hypothesis, alpha value, and write a conclusion. Make sure that you use appropriate terminology and specify whether you are using the classical method or the p-value method.
