The point estimate of the population mean is the sample mean, which is calculated by adding up all the values in the sample and dividing by the sample size. In this case, the sample mean is (16+19+18+17+20+18)/6 = 18. Therefore, the best choice is A, which corresponds to the point estimate of 18.0.
