A study was recently conducted on the reaction time of long -distance truck drivers (after two hours of non- stop driving). Assume reaction times (after two hours of non- stop driving) are known to be normally distributed, with a mean of 1.4 seconds and a variance of 0.0625 seconds. Reaction times would be recorded ( in seconds between the presentation of stimulus and braking) by subjecting a truck driver to a simulated environment. (a) what is sthe probability that a a particular truck driver who has been driving for two hours non-stop has a reaction time of : (i) more than two seconds?
