Question
The durations of the mating calls of a population of tree toads are normally distributed, with mean 182 milliseconds (msec) and standard deviation 30 msec. What proportion of these calls would be
expected to last between the following durations? (Round your answers to four decimal places.)
(a) between 122 and 242 msec
(b) between 227 and 272 msec
You may need to use the table of areas under the standard normal curve from the appendix.
