The reaction time of 1000 Rhesus monkeys was measured. The average time it took the monkeys to respond to a quickly moving object in their visual fields was .135 seconds, with a standard deviation of .021 seconds (assume a normal distribution). If one of the geriatric monkeys had a reaction time of .205 seconds, then that monkey’s reaction time is how many standard deviations from the mean?

A. 0 – 1 standard deviations

B. 1 – 2 standard deviations

C. 2 – 3 standard deviations

D. 3 – 4 standard deviations

E. 4 – 5 standard deviations

Kudos for correct

solution.
