Question

Five males with an X-linked genetic disorder have one child each. The random variable x is the number of children among the five who inherit the X-linked genetic disorder. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied.		x	P(x)
	0	0.033
	1	0.162
	2	0.305
	3	0.305
	4	0.162
	5	0.033

Does the table show a probability distribution? Select all that apply.

Yes, the table shows a probability distribution.

No, not every probability is between 0 and 1 inclusive.

No, the random variable x is categorical instead of numerical.

No, the random variable x's number values are not associated with probabilities.

No, the sum of all the probabilities is not equal to 1.

Find the mean of the random variable x. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

The table does not show a probability distribution.

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 + ...
