  • Challenge Question #2

    Will Hagan, Macalester College
    "It has been reported that less than 6 percent of all gray whale calves are born in Magdalena Bay each year. How many calves would that be?"

    Here are a few helpful hints:
    * Assume a total population of 23,000 gray whales and 15,000 mature adults.
    * Assume a 1:1 ratio of males to females
    * Assume that half of the females will bear young in a given year.

    (This question was asked as part of the March 5, 1997 Gray Whale Migration Update).
