Hypothesis Testing Name Course Instructor Date 1] Discuss probability. What is its history? What is the theory of probability? How is it calculated? What are the advantages and disadvantages of using this technique? Probability is concerned with understanding how chance affects certain outcomes of a random phenomenon (Michelson & Schofield, 2002). Probability and statistics are closely related, and probability predicts the likelihood that an event is likely to occur, but probability is a subset on the subject matter of statistics. Typically the probability that an event will occur is dependent on the likelihood that the event would occur in a number of ways as well as the final outcomes. Even though, probability has an element of uncertainty, when there are no known chances of occurrences, each event has equal chance among the outcomes. At the same time, probability distributions provide a clear picture of the population distribution. The normal distribution is then used in hypothesis testing as it may
