A scientist was asked to test the effect of a new vitamin for rats. His
hypothesis was that young rats that had vitamins added to their food would
gain weight faster than young rots fed a normal diet. He predicted that if
young rats were fed vitamins, then they would gain more weight by the end of
the experiment. He tested the effect of adding vitamins to some of the rats
diet by measuring the amount of weight each rat gained after three months
He then determined the average weight gained in each group to analyze his
results, he put the data he collected into the table shown below
What did the data show about the hypothesis?
A. The data supported the hypothesis
B. The data did not test the hypothesis
C. There was not enough dotato support of reject the typothesis
