The ordered pairs below give the winning times (in seconds) of a 100-meter freestyle swim race at a regularly-held competition from 1984 through 2012. (1984, 55.12)      (2000, 53.03) (1988, 54.13)   (2004, 53.04) (1992, 53.84)   (2008, 52.32) (1996, 53.70)   (2012, 52.20) (a) Sketch a scatter plot of the data. Let y represent the winning time (in seconds) and let  t = 84  represent 1984.         (b) Sketch the line that you think best approximates the data and find an equation of the line. (Round the slope and y-intercept to one decimal place.) y =        (c) Use the regression feature of a graphing utility to find the equation of the least squares regression line that fits the data. (Round the slope and y-intercept to two decimal places.) y =        (d) Compare the linear model you found in part (b) with the linear model you found in part (c). The models are not similar.The models are similar.

Which point is an outlier? Enter as an ordered pair, e.g., (x,y). (x, y) = b. Find the regression equation for the data set without the outlier. Enter the equation of the form mx + b rounded to three decimal places. ŷwo = c. Find the regression equation for the data set with the outlier. Enter the equation of the form mx + b rounded to three decimal places. ŷw == d. Is this outlier an influential point? Yes, the outlier appears to be an influential point. No, the outlier does not appear to be an influential point.
