  1. We use our F statistic to determine if we should accept or reject the null
  2. hypothesis. Where in this case the null hypothesis would be that the amount
  3. consumed by cows of food a, food b and c are all approximately the same which
  4. we're assuming means that cows do not prefer one type of food over the another.
  5. And the alternative is that they at least prefer one type of food over the
  6. other. So we have to compare our F statistic with the critical value. Use the F
  7. table to find this critical value and then decide, do we accept the null
  8. hypothesis or the alternative hypothesis.
