Researchers measured the reaction time to brake during a driving simulation.A sample of 20 healthy adults (age 55–65) had a mean reaction time = 0.72 sec, with standard deviation = 0.11 sec.A group of 18 adults diagnosed with Mild Cognitive Impairment (MCI) had a mean = 0.80 sec, with standard deviation = 0.15 sec.Using α = 0.025, test whether the MCI group has a significantly slower mean reaction time. assume that the standard deviation of both population is same.
