write a confidence interval or hypothesis test problem using this option. gather data and post your problem(without a solution) Think of a problem that deals with a comparison of two population means. Propose either a confidence interval or a hypothesis test question that compares these two means. For example you may want to know if the average weight of a rippled potatoe chip is the same as the average weight of a non rippled potatoe chip. You may weigh rippled regular potatoe chips from a large bag and find weights of 1.7, 1.9, 2.4, 1.3, 1.7, and 2.0 grams. You may weigh non rippled chips from another bag and find weights of 1.8, 1.6, 1.9, 1.9, and 1.4 grams. Assume a random sample was drawn.at the very bottom can you please give me the answer and inform me that that particular part is the answer. Thank you!!

Write a confidence interval problem using the option below. Gather the appropriate data and post your problem (without solution) in the discussion board. Once your initial post is complete, respond to your own post with the solution. Think about the population mean that you may be interested in and propose a confidence interval problem for this parameter. I believe the population mean number of times that adults ate fast food each week is 2.5. My data is after speaking to...

Write a hypothesis test problem using the option below. Gather appropriate data and post your problem (without a solution) in the discussion topic. Option 1: Think about a population mean that you may be interested in and propose a hypothesis test problem for this parameter. Gather appropriate data and post your problem. For example, you may believe that the population mean number of times that adults go out for dinner each week is less than 1.5. Your data could be...

write a hypothesis test problem. Post your problem with a solution. Option 1. Think about two population means that you may be interested in and propose a hypothesis test problem for this parameter. For example, you may believe that the average family size in Illinois is greater than the average family size in Wisconsin. Your data could be that you spoke with 20 people (10 in Illinois and 10 in Wisconsin) and found the following family sizes: 5, 6, 5,...

Write a confidence interval and hypothesis test using the word problem below. I am currently building a home gym in my garage and am not buying calibrated weight plates to reduce the overall budget. I want to know if the average weight of a 45lb steel plate is the same as a 45-lb concrete filled plate. I weighed seven steel plates and find weights of 44.8, 45.3, 45.0, 44.9, 44.7, 45.1, and 45.0lbs. I weighed seven concrete filled plates and...

indicate whether it is best assessed by using a confidence interval or a hypothesis test or whether the statistical inference is not relevant to answer it. What percent of university students support instituting a fall break? Do basketball players hit a higher proportion of free throws when they are playing at home than when they are playing away? Do majority of students who drive wear their seatbelts? On average, were the 23 players on the 2010 Canadian football team older...

In each problem show all steps of the hypothesis test or confidence interval. If some of the assumptions are not met, note that the results of the test or interval may not be correct and then continue the process of the hypothesis test or confidence interaval. Are there more children diagnosed with Autism Spectrum Disorder (ASD) in states that have larger urban areas over states that are mostly rural? In the state of Pennsylvania, a fairly urban state, there are...

Write a hypothesis test problem using one of the two options below. For whichever option you choose, gather appropriate data and post your problem (without a solution) in the discussion topic. You may use the same data that you gathered in your Module Three Discussion Topic post. Allow time for your classmates to post their solutions, and then respond to your own post with a solution for others to check their work. Option 1: Think about a population mean that...
