The mean of the sampling distribution is equal to the mean of the population, which is 80 pounds. The standard deviation of the sampling distribution is the population standard deviation divided by the square root of the sample size, which is 8 / √64 = 1 pound. However, the question only asks for the mean of the sampling distribution, which is simply equal to the mean of the population. Therefore, the best choice is A, 80.
