A survey of $1,200$ randomly selected restaurant owners found that $75\%$ believe offering vegetarian options improves customer satisfaction. Is this $75\%$ a population parameter or a sample statistic? Justify your answer.

The $75\%$ is a sample statistic because it is calculated from a subset of restaurant owners, not the entire population.

The $75\%$ is a population parameter because it represents the true proportion of all restaurant owners who believe vegetarian options increase satisfaction.

The $75\%$ is a sample statistic because it is an exact measurement of all restaurant owners.

The $75\%$ is a population parameter because the sample size of $1,200$ is sufficiently large to represent the whole population.
