You have recently been employed at the Centre for Disease Control and Prevention as Assistant Manager. The Manager has asked you to assist in preparing a report on assisted reproductive technologies (ART). ART includes all fertility treatments in which both the egg ad the sperm are used. According to data gathered from the Centre of Disease Control and Prevention, 0.7% of the ART cycles result in an ectopic pregnancy, 33.7% in a clinical pregnancy, and 65.6% results in no pregnancy.

You randomly selected 10 ART cycles for special review for the report. None of the cycles resulted in a clinical pregnancy. The Manager feels that it is impossible to select 10 ART cycles that did not result in a clinical pregnancy.

How would you determine if the Manager’s view is correct?

What probability distribution do you think best describes the situation? Why?

Write an explanation that answers the question, “Is it possible to select at random 10 ART cycles that did not result in a clinical pregnancy?” Include in your explanation the appropriate probability distribution and your calculation of the probability of no clinical pregnancies in 10 ART cycles.
