question 98

Short Answer

SCENARIO 5-1
The following table contains the probability distribution for X = the number of retransmissions
necessary to successfully transmit a 1024K data package through a network. $$\begin{array} { c | c | c | c | c | } X & 0 & 1 & 2 & 3 \\\hline P ( X ) & 0.35 & 0.35 & 0.25 & 0.05\end{array}$$
-Referring to Scenario 5-1, the variance for the number of retransmissions is ________.

Definitions:

Standard Deviation

The statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.

Margin of Error

A measure of the range of values below and above the sample statistic in a confidence interval.

Sample Mean

The average value of a sample set of numbers, estimated from a subset of a population.

Margin of Error

Represents the maximum amount by which the sample results are expected to differ from the actual population parameter.
