Here is data with y as the response variable. X 28.9 83.8 -122.7 51.1 65.5 3.9 28.1 -18.4 40.4 11.7 41.6 20.6 71.3 59.5 46.4 24.6 63.5 76.7 60 44.2 53.9 58.1 Make a scatter plot of this data. Which point is an outlier? Hint: Copy the data and paste them into Excel. Then select the two columns. Then click Insert and choose the scatterplot icon. (-122.7,-51.1) Enter as an ordered pair. For example (x,y) - with parenthesis. Find the regression equation for the data set with the outlier. Hint: Use Excel's =SLOPE(y_array,x_array) and =INTERCEPT(y_array, x_array) equations. Enter as an equation of the form # = by + bjI. Rounded to three decimal places. Do not include the hat in y-hat. Find the regression equation for the data set without the outlier. Hint: First delete the point. Then use Excel's =SLOPE(y_array, x_array) and =INTERCEPT(y_array, x_array) equations. 2 syntax error: this is not an equation. Enter as an equation of the form y = by + 61I. Rounded to three decimal places. Do not include the hat in y-hat. Is this outlier an influential point? O Yes, the outlier appears to be an influential point. O No, the outlier does not appear to be an influential point
