Tasks for Linear Regression Model (LR) (LR-1)Describe your topic provide your data and cite your source. Collect at least 8 data points.Label appropriately.TOPIC: To examine the Summer Olymipics Gymnastics Horizontal Bar competition Gold Medal winning results.Data was collected from the following website ~ http://www.databaseolympics.com/YEARPOINTS198019.825198420.00198819.919929.87519969.8520009.78720049.812200816.200(LR-2)Plot the points (x y) to obtain a scatterplot. Use an appropriate scale on the horizontal and vertical axes and be sure to label carefully. Visually judge whether the data points exhibit a relatively linear trend. (If so proceed. If not try a different topic or data set.)(LR-3) Find the line of best fit (regression line) and graph it on the scatterplot. State the equation of the line.(LR-4) State the slope of the line of best fit. Carefully interpret the meaning of the slope in a sentence or two.(LR-5) Find and state the value of r2 the coefficient of determination and r the correlation coefficient. Discuss your findings in a few sentences. Is r positive or negative? Why? Is a line a good curve to fit to this data? Why or why not? Is the linear relationship very strong moderately strong weak or nonexistent?(LR-6) Choose a value of interest and use the line of best fit to make an estimate or prediction. Show calculation work.(LR-7) Write a brief narrative of a paragraph or two. Summarize your findings and be sure to mention any aspect of the linear
