Answer 1

The sampling distribution of the sample proportion of individuals who had acne in their adolescent years is a normal distribution.

Step-by-step explanation:

The sampling distribution of the sample proportion of individuals who had acne in their adolescent years can be approximated by a normal distribution. This is known as the sampling distribution of the sample proportion.

The shape of the sampling distribution of the sample proportion is bell-shaped and symmetrical when the sample size is large enough.

For example, if we take multiple random samples of individuals who had acne in their adolescent years, and calculate the proportion of individuals in each sample who had acne, the distribution of these sample proportions will be approximately normal.
