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 44 Y, height 171 47 171 47 172 42 175 46 169 45 173 48 171 38 157 42 165 46 175 50 181 40 155 43 177 49 170 52 176 48 183 40 163 41 165 41 162 of a randomly selected set of skeletal remains + of a randomly selected set of skeletal remains + a) State the random variables. rv X= the length of metacarpal rv Y= the height b) The symbol and value of the correlation coefficient are as follows: Round final answer to 3 decimal places. = 0.746 relation between length of metacarpal and height for sets of Interpret this value: There is a strong positive skeletal remains. linear c) The symbol and value of the coefficient of determination are as follows: Round final answer to 3 decimal places.
