Ten young recruits were put through a strenuous physical training programme by the army. Their weights
(in kg) were recorded before and after with the following results:
Recruit 1 2 3 4 5 6 7 8 9 10
Weight before 127 195 162 170 143 205 168 175 197 136
Weight after 135 200 160 182 147 200 172 186 194 141
Using 5% level of significance, should we conclude that the programme affects the average weight of
young recruits (Answer using t-test as well as A-test)?

- Hypothesis testing is an act in statistics whereby an analyst tests an assumption regarding a population parameter.
- Hypothesis testing is used to assess the plausibility of a hypothesis by using sample data.
