Have the conditions for inference with a one-sample z-interval been met?

A) Yes, all conditions for inference have been met.

B) No, because the sample size is not large enough to satisfy the conditions for normality.

C) No, because the sample was not selected at random.

D) No, because the sample size is not less than 10 percent of the population size.
