Question

Question: A data set records the number of hours studied and the corresponding test scores. Study hours go from 1 to 8. The test scores for those hours are 52, 61, 58, 78, 82, 87, 89, and 95. Part a: Plot the data and identify any points that appear to be outliers. Part b: Determine a line of best fit for all 8 data points, and write the equation in the form y equals m x plus b. Part c: Determine a second line of best fit by removing the outlier or outliers, and write that equation. Part d: Compare the two lines. W…
