(by given).
The alternate hypothesis for the significance test states that the opposite of the null hypothesis(based on the claim )
∴ ![H_a:\mu](https://tex.z-dn.net/?f=H_a%3A%5Cmu%3C18)
The symbol "<" because we want to test if the maze is completed faster and thus if the time has decreased.
<h3>∴ option c)
