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 single value randomly selected from the distribution of W will vary from 4 by 3.5 attempted experiments. A single value randomly selected from the distribution of W will vary from 4 by 3.5 attempted experiments. A A single value randomly selected from the distribution of W will vary from 3.5 by 4 attempted experiments. A single value randomly selected from the distribution of W will vary from 3.5 by 4 attempted experiments. B Values of W typically vary from 4 by about 3.5 attempted experiments, on average. Values of W typically vary from 4 by about 3.5 attempted experiments, on average. C Values of W typically vary from 3.5 by about 4 attempted experiments, on average. Values of W typically vary from 3.5 by about 4 attempted experiments, on average. D The standard deviation of a random sample of values selected from the distribution of W will be 3.5 attempted experiments. The standard deviation of a random sample of values selected from the distribution of W will be 3.5 attempted experiments. E
