DZL DZL Instructions Data Analysis Project: Identify and Remove Relevant Points Part A - using technology In your spreadsheet file which you created for US_A2 assignment create a new tab and name it U8A4 . Identify one point on each scatter plot that has the greatest impact on the model by using residual plots as shown in the Unit 6 Lesson 4 Lesson o Residuals and Effect of Individual Points o Identify and remove relevant points . Create a new linear model for each models that you already created (find the new equation of the line of best fit and coefficient of determination R2 without relevant points . Save and submit your work as .xIsx file Part B - using a word processing software In your .doc file which you created for US_A2 assignment create a new heading Identify and remove relevant points o Describe the percentile that the point would be, if the data were normally distributed, by using the mean, standard deviation, and z-score. o Describe the impact of the point by comparing the new linear model to the original. Hint compare the coefficient of determination for each line of best fit with outliers and without outliers. . Save and submit your work as .docx or .pdf file
