8. When an anthropologist finds skeletal remains, they need to figure out the height of the person. The height of a person (in cm) and the length of their metacarpal bone (in cm) were collected and are in the table. (a) Use the regression equation to find the height of a person for a metacarpal length of 40 cm. (b) Find the correlation coefficient and coefficient of determination. Length of Metacarpal (cm) Height of Person (cm) 43 170 50 174 35 159 43 161 49 178 47 183 45 175 42 177 45 170
