B. There are a fixed number of trials.
C. The probability of “success” will vary for each trial for a given experiment.
D. The trials are all dependent each other.

8. What would be the mean value or expected value of a binomial random variable with 10 trials and 50% probability of success?

A. 1.0
B. 3.0
C. 5.0
D. 9.0

 

9. The shape of a binomial distribution depends on the number of trials and probability of success. Which of the following best describes the relationship among the shape, number of trials, and probability of success?

The higher the number of trials, the closer the shape of the distribution to the normal distribution.
B. The higher the probability, the closer the shape of the distribution to the normal distribution.
C. Both the number of trials and the probability should be high in order for the distribution to be closer to the normal distribution.
D. If the number of trials is high and the probability is about .50, the distribution will be closer to the normal distribution.
