Inferential statistics rely on probability and estimation to make projections about a larger population based on a smaller sample. As such, there is always a level of uncertainty associated with these projections, which is typically expressed through confidence intervals or p-values. However, by setting a predetermined level of uncertainty (e.g., a 95% confidence interval), we can use inferential statistics to make reasonably accurate projections even with smaller sample sizes. Therefore, choice A is the best answer.
