Which of the following best describes event A?Event A will always occur.Event A will never occurEvent A is very unlikely, but it will occur once in a while in a long sequence of trials.Event A will not occur more often than it will occur, but it is very likely.Question 3 of 7 Points: 10Which of the following represents the probability of an event that IS more likely NOTto occur, but its occurrence is not very rare.0.250.50.00.0050.75Question 4 of 7 Points: 10Suppose that P(A) = 0.65. Which of the following best describes event A?Event A will NOT occur more often than it will occur.Event A will occur more often than not, but it would not be unusual for event A not to occur.Event A will always occur.Event A will occur almost always except for extremely rare occasions.Question 5 of 7 Points: 10A ‘Statistics for the Natural Sciences’ course has 75 students: 22 Physics majors, 23 Chemistry majors, and 30 Biology majors.

Which of the following is true regarding the theoretical (classical) probability of getting a 5 and the empirical probability of getting a 5?The theoretical probability is 0.125 and the empirical probability is 0.15.The theoretical and empirical probabilities are both 0.125.The theoretical and empirical probabilities are both 0.15.The theoretical probability is 0.15 and the empirical probability is 0.125.Question 7 of 7 Points: 10While working on your statistics HW in a local coffee shop, you are approached by a stranger who puts a coin on the table and challenges you that the coin is fair. To test the stranger’s claim you start flipping the coin. Which of the following will provide the most convincing evidence that the stranger is trying to trick you and that the coin is actually not fair?You flip the coin 25 times and the coin shows ‘H’ in 15 out of the 25 flips.You flip the coin 150 times and the coin shows ‘H’ in 96 out of the 150 flips.You flip the coin 150 times and the coin shows ‘H’ in 90 out of the 150 flips.You flip the coin 25 times and the coin shows ‘H’ in 10 out of the 25 flips.
