Do freshmen really have the largest backpacks, or is that just a high school legend. Delenn was able to weigh a random sample of student backpacks throughout the school year.She also recorded the number of quarters of high school completed by the student who owned the backpack. Using spreadsheet software, Delenn created the following data representations: a) Write a sentence to describe the slope of ISRI, y= 13.84-055x r-0.66 the LSRL in a real-life context. 20 15 is b) What is the largest residual? c) What is the upper bound? d) What is the lower bound? e) Using the LSRL and the boundary lines, 10 0 0 7 0 4812 16 Quarters of H.S. Completed Quarters of HS. Completed estimate the range of expected values for a student who has completed 10 quarters to high school. Is the linear model the best choice for predicting backpack weight in this study? Use evidence from the data shown on the right to support your conclusion
