Topic: Interpreting Survey ResultsWhen the results of a survey or poll are published, the sample size and the margin of error should both be given. For example: 1000 voters were surveyed and 39±2% of the voters agree with the president. In this example N=1000 and the margin of error (MoE) is 2%.This website lists several public opinion polls. Search the site and find a poll where the sample size and margin of error are given. Try to find a poll dealing with a topic in your profession or one in which you are really interested.http://www.pollingreport.comMain Post: Determine the following information for the selected poll results and include in your initial post. See Example and DB starter video in Unit 6 LiveBinder.URL for the website. State the poll question, the sample size n, and the margin of error (also known as sampling error).Interpret the results of your poll using your own words and full sentences. Note: Depending on the question asked, your poll may have more than one poll result – you only need to discuss one result.State the confidence interval using the MoE. What does this confidence interval estimate?Use the Confidence Interval template (found in Unit 6 LiveBinder) to calculate the confidence interval based on the sample size and the number of successes (the proportion you are interested in). Use a confidence level of 95%.What is the calculated confidence interval? How does this compare to the interval in part 3 using the poll’s margin of error?Discuss potential biases that could skew sampling results.

Each swimmer is allowed to compete in 7 events at a swim meet. Danny got first place 3 times, second place 1 time, third 2 times, and fourth once. John got first 2 times, second place 3 times, third twice, and didn’t place fourth. Kenny didn’t place first, but was second once, third four times, and fourth two times. Sean placed first once, second twice, third three times, and fourth once. The club teams are waiting to see which trophy they will be getting. Their trophy is based on the amount of points each team received. Eagles Aquatics team had 8 people get first place, 9 in second, 10 in third, and 5 in fourth. The Pirates swim team had 6 people get first, 7 in second, 3 in third, and 1 in fourth. Devil Rays Aquatic Club had 9 people get first, 2 in second, 5 in third, and 7 in fourth. The Manta Rays swim team had 4 first place winners, 3 second, 2 third and 1 fourth. 1. First place receives 6 points, second 4, third 3, and fourth 2. Which swimmer got the most points? Which team won the trophy? Show how you found that out.2. Does it matter in what order you multiply the matrices? Explain.3. If you were to find out the total number of points scored by individuals and teams, how would you go about doing that?4. Look back at what you did for questions 1 and 2. How does this relate to your understanding of vectors?5. Come prepared to share another example of a problem in the real world that can be solved using matrices.

Option 2: Probabilities of Graduation and PublicationInstructionsIn the following study, three different universities have been tracking a select group of professors over the course of their employment at that university to determine the number of students who are in a particular professor’s classes, how many of those students have graduated, and if any of them have had their work published. In the attached Excel file, Probabilities, are the totals for each of the professors at the three different universities that participated in the study.The purpose of this study is to find the probabilities of graduation and publication for the students in the different professors’ courses. While a causal relationship may not be found between a professor and student graduation or publication, we need to rank the professors based on the different probabilities found with the data sets as described below.Prepare a report (see below) with your ranking of the professors based on the probabilities and conditional probabilities as well as the analysis of each university. Include the following seven (7) items in table format which is provided in the Probabilities file to support your ranking.Note: Be sure to use five (5) decimal places for your probabilities in the table, as some of them will be quite small. Do not convert to percentages as we are interested in probabilities only here. The overall probability of students graduating at each of the three universities. The overall probability of students having a publication at each of the three universities. The overall probability of students having a publication, given that they graduated at each of the three universities. The probability of a student graduating for each professor. The probability of a student having a publication for each professor. The probability of a student having a publication given that they graduated for each professor. Rank the professors within each university for each of the probabilities in 4–6. Then find the sum of the ranks and determine an overall ranking for each professor. Paper Requirements Items that should be included, but are not limited Items that should be included, at a minimum, are a title page, an introduction, a body which answers the questions posed in the problem, and a conclusion paragraph that addresses your findings and what you have determined from the data and your analysis. As with all written assignments, you should have in-text citations and a reference page. Please include any tables of calculations, calculated values, and graphs associated with this problem in the body of your assignment response.Note: You must submit your Excel file with your report. This will aid in grading with partial credit if errors are found in the report.
