The following situation calls for a significance test. State the appropriate null hypothesis <img src="https://tex.z-dn.net/?f=H

harina [27]

Answer:

$H_{0}: \sigma = 10\\$

$H_{a}: \sigma > 10\\$

Step-by-step explanation:

We are given the following in the question:

The organizers estimate that the variation in distance flown by the athletes will be σ = 10 meters.

This will be stated by the null hypothesis.

$H_{0}: \sigma = 10\\$

It was claimed that the organizers are underestimating the variation and the variation in distance is greater than 10.

This will be stated by the alternate hypothesis.

$H_{a}: \sigma > 10\\$

The parameter for the given hypothesis is standard deviation, $\sigma$ .
