It is used to test the hypothesis of an assumption that can be applied to a particular set or group of people.
In the question above, Option C is the valid conclusion because from the t-test carried out a significant level of 0.05 occured in two variables out of 85. Therefore there is insufficient evidence to prove that vitamin C improves the health of Adults.
