This question: Submit test 1 point(s) Previous question possible Test: Midterm Question 8 of 10 possible Examination In a recent year, the total scores for a certain standardized test were normally distributed, with a mean of 500 and a standard deviation of 10.5. Answer parts (a)(d) below. <:> (a) Find the probability that a randomly selected medical student who took the test had a total score that was less than 492. The probability that a randomly selected medical student who took the test had a total score that was less than 492 is D. (Round to four decimal places as needed.) (b) Find the probability that a randomly selected medical student who took the test had a total score that was between 495 and 510. The probability that a randomly selected medical student who took the test had a total score that was between 495 and 510 is El. (Round to four decimal places as needed.) (c) Find the probability that a randomly selected medical student who took the test had a total score that was more than 522. The probability that a randomly selected medical student who took the test had a total score that was more than 522 is El. (Round to four decimal places as needed.) (d) Identify any unusual events. Explain your reasoning. Choose the correct answer below. 0 A. The event in part (c) is unusual because its probability is less than 0.05. O B. None of the events are unusual because all the probabilities are greater than 0.05. O C. The events in parts (a) and (b) are unusual because their probabilities are less than 0.05. O D. The event in part (a) is unusual because its probability is less than 0.05
