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>
