One sample tests for proportions

Jair suspects that greater than

10 %

of the approximately

1,500

cars in the parking lot of a local concert hall are unregistered. To investigate, he takes a simple random sample of

100

of these cars, and finds that

25

of them are unregistered.

Are the conditions met for Jair to carry out a one-sample z-test for a proportion?

(Choice A)
No, because Jair did not sample randomly from the correct population of interest.
(Choice B)
No, because Jair sampled too many cars from the lot.
(Choice C)
No, because Jair sampled too few cars from the lot.
(Choice D)
No, because Jair may not reasonably assume that the sampling distribution of $\hat{p}$ ‍ is approximately normal.
(Choice E)
Yes.
