Minds On Do you think a taller person has a longer arm span than a shorter person?

Minds On 1.Was you prediction (hypothesis) correct? 2.Is there a relationship between height and arm span? 3.If a person is 160cm tall, what should their arm span be? 4.If a person has an arm span of 75cm, how tall are they?
