Using the proportions in the table, is the sample proportion an unbiased estimator?
Yes, the sample proportions are calculated using samples from the population.
Yes, the mean of the sample proportions is 0.6, which is the same as the population proportion.
No, 0.6 is not one of the possible sample proportions.
No, 70% of the sample proportions are less than or equal to 0.5.
