In a Study of Left- and Right-Handers' Reaction Times to Tones

question 12

Essay

In a study of left- and right-handers' reaction times to tones delivered to the right ear,
the right-handers' reaction times were approximately normally distributed with a
mean of 210 milliseconds and standard deviation of 40 milliseconds. The mean
reaction time for left-handers was 240 ms.
a) Sketch a normal distribution that describes right-handers' reaction times, and
locate the mean reaction time for left-handers in this distribution.
b) What proportion of right-handers reaction times would be faster than the mean
reaction time for left-handers?
