  • Story:

    Bjork Larsen was trying to decide whether to use a
    new racing wax for cross-country skis. He decided that the
    wax would be worth the price if he could average less than
    55 seconds on a course he knew well, so he planned to study
    the wax by racing on the course 8 times. The data report his race times.
