Question

predict the height of a womens whose humerus is 39 cm long

Answer 1

Don't know if this is correct or not but i think the answer is 160.75 cm long. Hope this helps.

Answer 2

I get h(39) = 2.75*39 + 71.48 = 178.73cm

h(32.46) = 160.75 -- ???

Also, in you description, it should read more like:

the function it described by h(x) = 2.75x+71.48 can be used to predict the height of a woman whose humerus (the bone from the womens elbow to the shoulder) is x cm long
