Refer to the Journal of Earthquake Engineering study of the time Y (in years) between major earthquakes occurring in the Iranian Plateau, Exercise 5.7. Recall that Y has the following density function:

a. Find Interpret the result.

b. Find the variance of Y.

c. Use the Empirical Rule to estimate

d. Find the actual probability, How does the answer compare to the result in part c?

Data From Exercise 5.7:

Earthquake recurrence in Iran. The Journal of Earthquake Engineering modeled the time Y (in years) between major earthquakes occurring in the Iranian Plateau. One of the models considered had the following density function:
