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 1|] 5 Answer pans (a)(d] below. (a) Find the probability that a randomly seleded medical student who took the test had a total score that was less than 487 The probability that a randomly seleded medical student who took the tat had a total score that was less than 48? is (Round to four decimal places as needed.) (b) Find the probability that a randomly seleded medical student who took the test had a total score that was between 499 and 514. The probability that a randomly seleded medical student who took the tat had a total score that was between 499 and 51 ii is (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 seleded medical student who took the test had a total score that was more than 522 is (Round to four decimal places as needed.) (d) Identify anyr 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. The events in parts (a) and (b) are unusual because their probabilities are less than I] 05 O C. The event in part {a} is unusual because its probability is less than 0.05. O D. None of the events are unusual because all the probabilities are greater than 0.05
