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.

H(o) : ∆ = 10

H(a) : > ∆ 10

Step-by-step explanation:

From the given information we could deduce the alternative hypotheses, we use the symbol for the population value. Proportion (p)

Mean (U)

Standard deviation (∆)

1. The null hypothesis states that the population value is = to the value mentioned in the claim

Therefore, H(o) : ∆ = 10

2. The alternative hypothesis states that the opposite of the null hypothesis (According to the claim)

H(a) : ∆ > 10

∆ is the population standard deviation of the distance flown by the athletes.
