In a survey of a group of men the heights in the 20 29 age group were normally distributed with a mean of 69 3 inches and a standard deviation of 3 0 inches A study participant is randomly selected Complete parts a through d below 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 Round to four decimal places as needed b Find the probability that a study participant has a height that is between 67 and 71 inches The probability that the study participant selected at random is between 67 and 71 inches tall is Round to four decimal places as needed c Find the probability that a study participant has a height that is more than 71 inches The probability that the study participant selected at random is more than 71 inches tall is d Identify any unusual events Explain your reasoning Choose the correct answer below Round to four decimal places as needed A The events in parts a and c are unusual because its probabilities are less than 0 05 OB The event in part a is unusual because its probability is less than 0 05 OC The events in parts a b and c are unusual because all of their probabilities are less than 0 05 D There are no unusual events because all the probabilities are greater than 0 05
