Ski jump When ski jumpers take off, the distance they fly varies considerably depending on their speed, skill, and wind conditions. Event organizers must position the landing area to allow for differences in the distances that the athletes fly. For a particular competition, the organizers estimate that the variation in distance flown by the athletes will be s = 10 meters. An experienced jumper thinks that the organizers are underestimating the variation.

Answer :

Based on the information, the null hypothesis is that variation in distance flown by the athletes will be s = 10 meters.

Null hypothesis.

It should be noted that the null hypothesis simply states the population parameter. In this case, the null hypothesis is that the variation in distance flown by the athletes will be s = 10 meters.

The alternate hypothesis is that the variation in distance flown by the athletes will be more than s = 10 meters.
