Assume a population of 40, 45, 47, and 53. Assume that samples of size n = 2 are randomly selected with replacement from the population. Listed below are the sixteen different samples.

Find the Sample Median and Probability of each grouping, and then compare the population median to the mean of the sample medians. Choose the correct answer below.

	A.	The population median is equal to half of the mean of the sample medians.
	B.	The population median is equal to double the mean of the sample medians.
	C.	The population median is equal to the mean of the sample medians.
	D.	The population median is not equal to the mean of the sample medians (it is also not half or double the mean of the sample medians).

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
