10. For each of the following scatterplots, determine if there are any obvious outliers. If there are outliers, determine if they are influential observations. (a) Scatterplot 1 (b) Scatterplot 2 (c) Scatterplot 3 11. The following table shows the mean and standard deviations of two variables x and y. y Mean 5.2 10.9 Standard Deviation 1.93 2.54 It is given that x and y are negatively correlated with r2 = 0.974. Determine the equation for the least-squares regression line between a and y. Round the slope and y-intercept to three decimal places
