A park ranger wanted to compare the length of largemouth bass in two different lakes in a park. He randomly pulled 20 largemouth bass from each lake and measured the length of each fish. The table shows the mean length and the mean absolute deviation (MAD) of the largemouth bass in each lake. Lake Mean (in.) MAD 1 16 2 2 22 2 Calculate the means-to-MAD ratio. Can the park ranger conclude that the largemouth bass in Lake 2 are generally longer than the ones in Lake 1? Select from the drop-down menus to correctly answer the question. The park ranger conclude that Lake 2 generally has longer largemouth bass because the distributions of lengths in the two lakes are .

Part one: measurements 1. measure your own height and arm span (from finger-tip to finger-tip) in inches. you will likely need some from a parent, guardian, or sibling to get accurate measurements. record your measurements on the "data record" document. use the "data record" to you complete part two of this project. name relationship to student x height in inches y arm span in inches archie dad 72 72 ginelle mom 65 66 sarah sister 64 65 meleah sister 66 3/4 67 rachel sister 53 1/2 53 emily auntie 66 1/2 66 hannah myself 66 1/2 69 part two: representation of data with plots 1. using graphing software of your choice, create a scatter plot of your data. predict the line of best fit, and sketch it on your graph. part three: the line of best fit include your scatter plot and the answers to the following questions in your word processing document 1. 1. which variable did you plot on the x-axis, and which variable did you plot on the y-axis? explain why you assigned the variables in that way. 2. write the equation of the line of best fit using the slope-intercept formula $y = mx + b$. show all your work, including the points used to determine the slope and how the equation was determined. 3. what does the slope of the line represent within the context of your graph? what does the y-intercept represent? 5. use the line of best fit to you to describe the data correlation.
