Question 1 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 for 19 sets of skeletal remains. The data are in the table below. X, length of metacarpal (in cm) | Y, height (in cm) 46 175 44 173 50 181 48 171 49 170 52 176 48 183 42 161 42 165 44 171 46 169 39 159 43 170 47 175 43 177 40 160 47 171 41 165 42 175 a) State the random variables. rv X = a randomly selected set of skeletal remains v of the length of metacarpal rv Y = the mean length of metacarpal of a randomly selected set of skeletal remains vc) Find the equation of the best-fitting line (the least squares regression equation). Round values to 2 decimal places. Include the restricted domain. equation: Ny X restricted domain: cm
