(a) Find the probability that a study participant has a height that is less than 67 inches. The probability that the study participant selected at random is less than 67 inches tall is 0.3632. (Round to four decimal places as needed.) (b) Find the probability that a study participant has a height that is between 67 and 70 indches. The probability that the study participant selected at random is between 67 and 70 inches tall is 0.5118. (Round to four decimal places as needed.) (c) Find the probability that a study participant has a height that is more than 70 inches. The probability that the study participant selected at random is more than 70 inches tall is 0.1251. (Round to four decimal places as needed.) (d) Identify any unusual events. Explain your reasoning. Choose the correct answer below. A. The events in parts (a), (b), and (c) are unusual because all of their probabilitios are less than 0.05. O B. The events in parts (a) and (c) are unusual because its probabilities are less than 0.05. O C. There are no unusual events because all the probabilities are greater than 0.05. O D. The event in part (a) is unusual because its probability is less than 0.05.
