Repeat part a, but this time delete the last point. c. Draw a graph of the data, and use it to explain the dramatic difference between the answers to parts a and b. a. The least squares line is Y = 0.9252x + .6395 . (Use integers or decimals for any numbers in the expression. Round to four decimal places as needed.) The correlation coefficient r is .9549 . (Type an integer or decimal rounded to four decimal places as needed.) b. After deleting the last point, the least squares line is Y = (Use integers or decimals for any numbers in the expression.
