To estimate the height of the woman whose humerus is 30.93 cm long, we need to substitute x=30.93 into the given function F(x) = 2.75x + 71.48:
F(30.93) = 2.75(30.93) + 71.48
F(30.93) ≈ 156.5375
Rounding the answer to four decimal places, we get 156.5375 cm as the estimated height of the woman. Therefore, the best choice is A). We can use the given function F(x) = 2.75x + 71.48 to estimate the height of a woman whose humerus is x cm long.

Substituting x = 30.93 in the function, we get: 
F(30.93) = 2.75(30.93) + 71.48 = 156.5375

Therefore, the estimated height of the woman is 156.5375 cm. Rounded to the nearest four decimal places, the answer is 156.5375 cm. Thus, the best choice is A).
