The Geometric Distribution Quiz
O
Let W represent the number of attempted experiments to get one experiment that is not successful.
The random variable W has a geometric distribution with mean 4 and standard deviation 3.5. Which of the following is the best interpretation of the standard deviation?

A:
A single value randomly selected from the distribution of W will vary from 4 by 3.5 attempted experiments.

B
A single value randomly selected from the distribution of W will vary from 3.5 by 4 attempted experiments.

C
Values of W typically vary from 4 by about 3.5 attempted experiments, on average.

D
Values of W typically vary from 3.5 by about 4 attempted experiments, on average.

E
The standard deviation of a random sample of values selected from the distribution of W will be 3.5 attempted experiments.
