The following data comes from an experiment performed to determine if there is a relationship between the percentage of blood hemoglobin (H) in dogs and the number of red blood cells (C) they possess. Use a graphing calculator to find the equation of the line which best fits the data and gives the number of red blood cells (in millions per mm) as a function of the percentage of blood hemoglobin (C = mH + b). Also find the correlation coefficient for this scientific data and discuss whether or not the line is a good model for the data. Blood hemoglobin % 93 99 96 5 80 80 98 Red blood cells 8.4 8.5 8.1 6.2 7.9
