Essay
In a study of the reaction times of left- and right-handers' reaction times to tones delivered to the right ear, the right-handers' scores were approximately normally distributed with a mean of 240 milliseconds and standard deviation of 32 milliseconds. The mean score for right-handers was 210 ms.
a) Sketch a normal distribution that describes left-handers' reaction times, and locate the mean reaction time for right-handers in this distribution.
b) About what proportion of left-handers reaction times would be "better" (i.e. smaller) than the mean reaction time for right-handers?
