Using Proportionality

How do figure out the average heights and weights for sheep and cows? Also. for Bald Eagles and Canada Geese.

Dairy Cow 5 to 6 feet tall at the shoulder/weight 500lbs
Bighorn Sheep Shoulder Height: 2.5 to 3.5" 280-300 weight

Canada Goose
length: M 25-45 inches/weight: M 3-13 lbs.

Bald Eagle
length 28–40 in
weight 5.5 and 15 lb

You keep asking this, but it keeps being vague.

If we assume that all animals are evenly distributed in the height/weight ranges, then just use the average of the low and hi values.

For example,
Bighorn Sheep range from 2.5 to 3.5 feet high. The average would be (2.5+3.5)/2 = 3' high. The weight ranges from 280-300 lbs. The average would be (280+300)/2 = 290 lbs.

Do the same for the other animals. If there's more to the question (like how proportionality figures in), please clarify.
