Answer:
b. A hypothesis that is not supported by the data that has been collected and analyzed is rejected.
Explanation:
A hypothesis is done by stating null and alternative hypotheses. Then the data collected is analyzed if the claim in null hypothesis is true or not.
If not, then data does not support the null hypothesis is and it is rejected in favor of alternative hypothesis.
To reject, test result has to be significant, otherwise it means data does not support alternative hypothesis and it has to be rejected.
