This would be test of independence because it contain only one sample test

Step-by-step explanation:

Test of independence determine two factors are independent or not

For example

if we do a test of independence

null hypothesis : H 0: Being a cell phone user while driving and receiving a speeding violation are independent events. If the null hypothesis were true, we would expect about 28 people to use cell phones while driving and to receive a speeding violation.

Therefore in the given question Each respondent answer that it might be in "Right Direction " or "Wrong Direction".

So it is a independent test.
