in a survey of U.S. adults with a sample size of 2001, 314 said Franklin Roosevelt was the best president since World War II Two US adults are selected at random from this sample without replacement Complete parts (a) through ( (a) Find the probability that both adults say Franklin Roosevelt was the best president since World War The probability that both adults say Franklin Roosevelt was the best president since World War is is (Found to three decimal places as needed) (b) Find the probability that neither adult says Franklin Roosevelt was the best president since World War The probability that neither adult says Franklin Roosevelt was the best president since World War [ (ound to three decimal places as needed) Find the probability that at least one of the two adults says Franklin Roosevelt was the best president since World War The probability that at least one of the two adults says Franklin Roosevelt was the best president since World War it is (Round to three decimal places as needed) (4) Which of the events can be considered unusual? Explain. Select all that apply Submit test The event in part () is unusual because its probability is less than or equal to 0.05. The event in part() is unusual because is probability is less than or equal to 0.05 None of these events an unusual The event in part (c) is unusual because its probability is less than or equal to 0.05
Previous question In a survey of a group of men, the heights in the 20-29 age group were normally distributed, with a mean of 69.6 inches and a standard deviation of 2.0 inches. A study participant is randomly select (a) Find the probability that a study participant has a height that is less than 65 inches. The probability that the study participant selected at random is less than 65 inches tall is (Round to four decimal places as needed) (b) Find the probability that a study participant has a height that is between 65 and 72 inches The probability that the study participant selected at random is between 65 and 72 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 72 inches. The probability that the study participant selected at random is more than 72 inches tall is (Round to four decimal places as needed.) (d) identify any unusual events. Explain your reasoning. Choose the correct answer below. OA The event in part (b) is unusual because its probability is less than 0.05 OB. The events in parts (b) and (c) are unusual because its probabilities are less than 0.05 C. None of the events are unusual because all the probabilities are greater than 0.05. OD. The event in part (a) is unusual because its probability is less than 0.05 Time
