Thank you for the opportunity to help you with your question!

The claim: 53% of people use seatbelts when riding in a car.

Null hypothesis: In this particular case, because there is no second claim made, I would say that the null hypothesis is the claim. It's a statement of equality.

Alternative hypothesis: Less than 53% of people surveyed use seatbelts when riding in a car.

Please let me know if you need any clarification. I'm always happy to answer your questions.
