3. Here are data on the number of malpractice claims filed, per 100 physicians, by field, for 1985 and 1992. We want to predict number of claims in 1992(Y) using the data in 1985(X). Find mean, standard deviation of each column using the formulas. Then find correlation for the following data. Finally write the least squares-regression line to predict Y using formula. Graph LS-regression line on the scatter-plot. Specialty 1985 1992 X Y Family Practice 5.7 6.7 Internal medicine 6.2 7.3 Surgery 16.8 15.6 Pediatrics 7.2 6.9 Obstetrics 25.8 14.8 Radiology 12.8 11.1 Psychiatry 2.9 2.4 Anesthesiology 7.5 4.1 Pathology 4.1 3.1 Mean of X : Mean of Y: Standard deviation of X: Standard deviation of Y:Correlation of X and Y: Show LS Regression Line to predict Y: Find Slope: Intercept: Predict Y using when X is 25.8. Then find the residual. Predict Y using when X is 6.0. Then find the residual. Explain! Show scatterplot and LS-Regression Equation
