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 6 Answer parts (a)(d) below (1)- A (a) Find the probability that a randomly selectedlmedical student who tick the test had a total score that was less than 492 l 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.) [ . i (b) Find the probability that a randomly selected medical student who took the test had' a total score that was between 496 and 509 l The probability that a randomly selected medical student who took the test had El total score that was between 496 and 509 is D (Round to four decimal places as needed.) to) Find the probability that a randomly selected medical student who tookthe test had a total- score that was more than 523. The probability that a randomly selected medical student who took the test had a total score that was more than 523 is '3 (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 l O B. The event in part (a) is unusual because its probability is less than 0.05. ' L O C The events in parts (a) and (b) are unusual because their probabilities are less than at 05 'l O D. None of the events are unusual because all the probabilities are greater than '0 05
