Question
Please see below. I need this asap. Just need help with the population correlation part.
The following data can be copy-pasted into Geogebra. Highlight all of the table data below and copy (CTRL-C should work here): Open Geogebra and choose "Spreadsheet." You can also get to the Spreadsheet through the "View" menu. Close the Algebra and Graphics displays if they are showing; we won't need them. Now select an empty cell in the Geogebra spreadsheet. Do not select an entire row or column! Paste the copied data (CTRL-V should work). The data will be pasted into two rows in the spreadsheet. x 14 15 18 27 38 64 65 69 72 73 75 77 81 85 90 91 94 97 97 99 y 88 29 22 6422 14 52 22 29 13 64 48 76 35 84 68 36 28 51 78 In the Geogebra spreadsheet, select both rows. On the top menu bar, find the "One Variable Analysis" button (it's the second large button from the left, and looks like a small blue bar graph). Carefully click the small triangle in the lower-right corner of the button, and select "Two Variable Regression Analysis" from the drop-down menu. Click “Analyze" in the new window to get a scatterplot. In the Data Analysis window, click the Ex button just above "Scatterplot." This brings up the Statistics sidebar. We've used this for Histograms, but a different set of statistics will appear here. To check that you've done things correctly: • Enter the MeanX Value: 67.05 • Enter the MeaxY Value: 46.15 • Enter the sample correlation: r = 0.1285 • Enter the population correlation: p = 0.12850
