Question 1 In June, 2021, Gallup published an online article titled Public Backs Requiring COVID-19 Vaccine to Attend School (Links to an external site.) by Jeffrey M. Jones. According to the article, 61% of U.S. adults who responded to the survey favor requiring College students to be vaccinated in order to attend classes (including classes in fall 2021). A representative random sample of 3,572 adults U.S. adults, aged 18 and older, were surveyed. Are conditions met for calculating a confidence interval? Support your conclusion mathematically and show your work. If conditions are met, use your graphing calculator to calculate a 95% confidence interval that estimates the proportion of U.S. adults who favor requiring College students to be vaccinated in order to attend classes. State your results in context. Question 2 Login and open StatCrunch (directions). Open your IAT sample data set in StatCrunch (directions) We will use a 90% confidence interval to estimate the population proportion of participants born-female in our chosen IAT data set. So, you are tasked with using your IAT sample to calculate a 90% confidence interval that estimates the population proportion of participants born-female in your particular IAT. But, you are missing a piece of information that would allow you to use your graphing calculator to find the confidence interval. What piece of information is missing? Even though we cannot readily use our graphing calculators, StatCrunch can calculate the confidence interval for us! Use StatCrunch to find the 90% confidence interval for the population proportion of female participants in your particular IAT (directions - opens in a new tab). Highlight and copy everything in your StatCrunch output window and paste it in your response. Identify the sample proportion (?? )(p^) in the StatCrunch output table. Then determine whether conditions are met for using the confidence interval to estimate the population proportion of female participants in your chosen IAT. Show your work. If conditions are met, estimate the population proportion of female participants in your particular IAT, and state your conclusion in context. If conditions are not met, explain what a researcher could do so that conditions are met. Based on your analysis, do you think the population of participants in your chosen IAT are representative of the U.S. population? Explain. https://www.statcrunch.com/app/index.php?dataid=38...

FST Chapter 7: Probability and Simulation There are 27 questions from the Chapter Review on pages 482-485 of our textbook (see attachments). **Helpful tip: There are answers to the odd numbered questions in the back of the textbook. Use these to help you make sure you are on the right track for the questions on the assignment (see attachments). At the end of the assignment, there are an additional 10 questions that are not from the textbook. Show your work and circle your answers for each question below. If your answer is not correct I will look at your work to see if I can award partial credit. You may attach your work to this as long as you clearly mark which problem is being worked. When you are finished you should scan or take photos of the pages and send back to me. I suggest using the Camscanner app (free version) or a similar program so that you can attach your entire assignment as 1 file. When using this app, select the batch function so that you can take multiple pictures. Please take any photos in bright light so that your answers and work show up clearly - then submit it as a PDF file. It is okay to hand write work/answers, as long as it is clear what work belongs with what question and the answers are circled. The assigned questions are in the attachments.
