The board of examiners that administers the real estate broker's examination in a certain state found that the mean score on the test was 494 and the standard deviation was 72. If the board wants to set the passing score so that only the best 10% of all applicants pass, what is the passing score? Assume that the scores are normally distributed. Round to the nearest whole number.

John Beale of Stanford, California, recorded the speeds of cars driving past his house, where the speed limit read 20 mph. The mean of 100 representative readings was 23.76 mph, with a standard deviation of 3.53 mph. a) How many standard deviations from the mean would a car going the speed limit be? b) Which would be more unusual, a car traveling 35 mph or one going 8 mph? a) A car traveling at the speed limit is from the mean. (Round to two decimal places as needed.) b) Choose the correct answer below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) OA. B. standard deviations O C. The car traveling 35 mph is more unusual. It is standard deviations from the mean, while the car traveling 8 mph is standard deviations from the mean. The car traveling 8 mph is more unusual. It is standard deviations from the mean, while the car traveling 35 mph is standard deviations from the mean. Both cars are equally unusual. Both cars are standard…
