Plug in x = 30.93 into the given function: F(30.93) = 2.75(30.93) + 71.48 = 156.54 cm (rounded to four decimal places). Therefore, the estimated height of a woman whose humerus is 30.93 cm long is 156.5375 cm. The correct answer is B. Substitute x = 30.93 into the function F(x) = 2.75x + 71.48 and simplify:
F(30.93) = 2.75(30.93) + 71.48 ≈ 156.5375
Therefore, the estimated height of the woman is 156.5375 cm, rounded to four decimal places. The correct choice is B.
