Of the students randomly chosen for your data set, what percent of students do not work any amount? Sort the Work column in ascending order to easily find the number of students who do not work and use that value to create a percentage.  Watch this short video to learn how to sort the work column (Links to an external site.) in your data set. Use the percentage in part a) to create a 95% confidence interval estimate for the percentage of all college students who do not work. (see concepts in Unit 7 – Modules 17-19) Show your work. You can either use the math-type feature in Microsoft Word to write out your steps or you can take a picture of your handwritten work and paste it into the Word document. Interpret your confidence interval in complete sentences. “We are 95% confident that…” What is the margin of error for the confidence interval you found? What could you do to make the confidence interval more precise/smaller?  Explain using complete sentences. the table https://www.statcrunch.com/app/index.php?dataid=37...

Project Week 3Project 3 Instructor’s Notes:You have seen the data in previous assignments. There are two questions—the second one has four parts. The project is a little confusing in the way it is written, so here is the clarification.1. The first is a short answer.2. The second, following on from the first question, asks for the analysis of a histogram for each major for private and public universities (4 histograms—a public and a private one for each major)—it will help if you use Excel to do a graph to help in your analysis. Make sure to analyze “Annual % ROI,” not some other column.For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadheet. Download it here. Using the ROI data set:If we select 7 colleges from a major and then record whether they are of ‘School Type’ ‘Private’ or not, is this experiment a binomial one? Why or why not?For each of the 2 majors determine if the ‘Annual % ROI’ appears to be normally distributed. Consider the shape of the histogram and the measures of central tendency (mean and median) to justify your results. Report on each of these with charts and calculations to justify your answers.
