When a sample is selected at random from a population, the sample mean will likely be: A. larger than the population mean, B. smaller than the population mean, C. different from the population mean, or D. equal to the population mean

Solution

I think the author intends to hear answer (D) because sample mean is an unbiased estimator of population mean, but to be real, the technically correct answer is (C) , (unless mean is equal to mode with discrete distribution case)
