The probability that the study participant selected at random is between 67 and 71 inches tall is __

(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. A)Therearenounusualeventsbecausealltheprobabilitiesaregreaterthan 0.05.

B)The events in part (a) and (c) are unusual because its probabilities are less than 0.05

C) The events in part (a) (b) and (c) are unusual because all of their probabilities are less than 0.05

D)The event in part (a) is unusual because its probability is less than 0.05.
