Answer:

<h3>Option c) $H_a:\mu$ is correct</h3><h3>The alternate hypothesis for the significance test is $H_a:\mu$ </h3>

Step-by-step explanation:

The alternate hypothesis use the sumbol for the population value

Let p be the proportion , Mean be $\mu$ and stadard deviation be $\sigma$

The null hypothesis states that population value is equal to the value mentioned in the given claim.

$H_0:\mu=18$ (by given).

The alternate hypothesis for the significance test states that the opposite of the null hypothesis(based on the claim )

∴ $H_a:\mu$

The symbol "<" because we want to test if the maze is completed faster and thus if the time has decreased.

<h3>∴ option c) $H_a:\mu$ is correct.</h3>
