In a psychological testing experiment, 25 subjects are selected randomly and their reaction time, in seconds, to a particular simulus is measured. Past experience suggests that the variance in reaction times to these types of stimuli is 4 sec^2 and that the distribution of reaction times is approximately normal. The average timw for the subjects is 6.2 seconds. Give an upper 95% bound for the mean reaction time.
