The first Batman movie was made over 50 years ago in 1966. Over the years, Batman has been played on screen by a number of actors and even by a Lego figure in the Lego Batman movies. In the original comic books, Batman was 188 centimeters tall (about 6'2") and weighed 95 kilograms (about 210 pounds).

(c) The observation for Lego Batman (4, 0.005) is far removed from the other values in the data set (not surprising!). Is this observation influential in
determining either the slope of the least-squares line, or the intercept, or both? Justify your answer. (Round your answers to four decimal places.)
This point ---Select--- influential in determining the slope. This point ---Select--- influential in determining the intercept. That point ---Select--- far
removed from the other points in both the x and y directions. Removing the Lego Batman point, the equation of the least squares regression line is
