A marketing representative wants to estimate the proportion of people in a state who like the new design on the packaging of a certain cleaning product. The representative interviewed 100 people at a certain supermarket, and 82 people indicated that they liked the new design. Have the conditions for creating a confidence interval for the population proportion been met?

Yes, because the sample was selected at random.

A
Yes, because sampling distributions of population proportions are modeled with a normal model.

B
Yes, because the sample is large enough to satisfy the normality conditions.

C
No, because the sample is not large enough to satisfy the normality conditions.

D
No, because the sample may not be representative of all people in the state.
