      Probability is the chance or likelihood of an event occurring. We will study two types of probability, theoretical and experimental. Theoretical Probability: the probability of an event is the ratio or the number of favorable outcomes to the total possible outcomes. P(Event) = Number or favorable outcomes Total possible outcomes. Sample Space:

      (3) 2-Tail, p-value = .0029 is for testing if the proportion of women with the potential risk factor differs between the two groups. The fact this p-values is significant suggests that the proportion of women having a first pregnancy at or before the age of 25 is not the same for both groups.

      (a) Using a 10% level of significance, find the critical region for a two-tailed test to answer the manager’s question. You should state the probability of rejection in each tail which should be less than 0.05. (5) (b) Write down the actual significance level of a test based on your critical region from part (a). (1)
