Reaction time tests assess a person's quickness to react to a stimulus. These tests measure how quickly a person can click a mouse button or tap on a screen when a dot appears on a screen. Pharmaceutical researchers are investigating the side effects of a new cold medication. They decide to use a reaction time test that is known to have results that are normally distributed with a mean score of 199. They recruit a random sample of 13 healthy adults who are given a dose of the cold medication. One hour later, the subjects each complete the reaction time test. The sample mean reaction time is calculated to bex=205 with standard deviation s=19.27. The researcher wants to conduct a hypothesis test to find out whether the mean reaction time is higher after a dose of the cold medication. Thetest statisticfor the hypothesis test is1.122642.What is theP-valuefor this test? Give your answer to4 decimal places.
