Answer
(a) See the image below
(b) $y=1.88x+82.65$ (Red line graph on the image below)
(c) $182.3cm$
Work Step by Step
(a) We simply input all the data provided (See the image: blue dots)
(b) Using the Regression Line Calculator, we can calculate the equation of the regression line and then graph it: $m=1.88074\approx1.88$ $b=82.64974\approx82.65$ So, we will get the linear equation:
$y=1.88x+82.65$
(c) To calculate how tall the person was according to his femur of $53cm$, we can simply input it into the equation formed in (b): $y=1.88x+82.65$
$y=1.88\times53 + 82.65=182.29\approx182.3$
