2. Cow Growth Rates

A type of feed claims to boost the growth rate of cows. The feed is tested on two twin newborn cows. Bessie

receives the experimental feed, and Bertha receives regular corn feed. Their weights are recorded below.

Graph the data below. Use a dotted line for Bessie and a straight line for Bertha. Make sure you label the X

and Y Axis of the graph

Both cows ended at the same weight, but did the experimental feed change the way they gained weight at all?

Describe your conclusions about the experimental feed and explain why it is important that the experiment

used twin cows?
