(5 paints} Step 9: Make a short video (2 7 3 minutes) presenting your results, Separate assignment In Canvas for 10 points. Math 1342 Project - Spring 2023 90 possible points + Video (10 possible points) Directions: Show all work - NEATLY. Clearly identify answers. No late assignments accepted! Step 1: Identify your population. Use Appendix B in our textbook or the ebook. Choose one of the quantitative variables (weight, serum cholesterol, systolic pressure, IQ or sodium). (6 points) Step 2: Conduct a systematic sample of 30 from this population. To do so, roll a die to determine which number to start with, then choose every 3"d data item for your sample. Identify your starting number and list the resulting sample data set. (10 points) Step 3: Find the following descriptive statistics. Round to one decimal place. Show or explain how you found the statistic. (4 points each) a.) Mean b.) Median c.) Mode d.) Midrange e.) Range f.) Variance g.) Standard deviation h.) 5 number summary i.) Upper fence j.) Lower fence k.) Identify any outliers or say NONE if there aren't any. 88
