Archaeologists Often Find Only Parts of Ancient Human Remains

Multiple Choice

Archaeologists often find only parts of ancient human remains. For example, they may find a small finger bone, called the metacarpal bone. Is it possible to predict the height of a human from the length of a metacarpal bone? To investigate, a researcher measures the heights and metacarpal lengths of 200 adults. In making the scatterplot, the researcher should:

A) plot the height of the person on the horizontal axis.
B) plot the metacarpal length on the horizontal axis.
C) first determine if the heights of humans follow a Normal distribution.
D) use a plotting scale that makes the overall trend roughly linear.
