(a) Suppose the population standard deviation is 6. If we select one sample of size 25 from the population, then on average, the deviation between the sample mean and the population mean is (b) Now, if we select a larger sample of size 100 from the same population, the deviation between the sample mean and the population is (c) Therefore, the larger the sample size, the (farther or closer?) the sample mean is to the population mean on average.

Regarding the importance of sample size (n):
(a) Suppose the population standard deviation is 6.
If we select one sample of size 25 from the
population, then on average, the deviation
between the sample mean and the population
mean is
(b) Now, if we select a larger sample of size 100
from the same population, the deviation
between the sample mean and the population
is
(c) Therefore, the larger the sample size, the
(farther or closer?) the sample mean is to the
population mean on average.
