Suppose That the Duration of the Mating Calls of a Population

question 97

Multiple Choice

Suppose that the duration of the mating calls of a population of tree toads are normally distributed, with mean 188 milliseconds (msec) and standard deviation 40 msec. What proportion of these calls would be expected to last between 192 and 268 msec? Use a table of the standard normal distribution to solve the problem. Round your answer to four decimal places. ​

• A)0.5626
• B)0.9374
• C)0.4374
• D)0.1874
• E)0.1750
