A psychologist is interested in identifying the reaction of human behaviour under a stressful circumstance (fight or flight behaviour). It is known that, when using a particular method for measurement, the accuracy ratings of people in the general population (those that stay calm) are normally distributed with an average or mean of 60 and a variance of 44. In this study, psychologists aim to test 40 people who are prone to fight (military). The mean accuracy of these individuals was 62. Using = 0.05 for a one-tailed Z-test, what should the psychologist conclude for the sample?
