Passage

Read the following paragraph and answer the five questions which follow:

A researcher in experimental psychology hypothesized that a particular ‘Reward System’ for fast reactions would improve the reaction time. To verify this hypothesis, he selected forty subjects in the age range of 25 to 35 years from an organization. Following the standard reaction time experiment, he measured the simple reaction time without the reward system. While taking each trial in the experiment, the time-interval between the ready signal and the onset of stimulus was randomly varied between two to five seconds. In the second part of the experiment, the reward system was introduced and the simple reaction time was measured again for the same subjects. The mean reaction time before the introduction of reward system was 210 milliseconds and the mean reaction time after the introduction of reward system was 250 milliseconds. The difference between the two means was statistically significant at . 01 level.
