Consider the following prediction.
prediction: if cows need to eat protein to build muscle tissue, then an
increase in the amount of protein in a cow's diet will result in an increase in
the average weight of a cow over a two-year period.
which of the following best describes this prediction?
o
a. the hypothesis is not useful because it is too long as a sentence
and therefore difficult to read.
o
b. the prediction is useful because it proves that the hypothesis is
true before any data have been collected.
o
c. the prediction is useful because it specifies what observations
will be made to test a hypothesis.
o
d. the prediction is not useful because scientists are skeptical of
anyone who claims to see into the future.
