Quantitative SAT scores are approximately Normally distributed with a mean of 500 and a standard deviation of 100. Choose the correct technology output for finding the probability that a randomly selected person scores less than 449 on the quantitative SAT and report the probability as a percentage. a. Click the link to view technology output 1 of 2. b. Click the link to view technology output 2 of 2. . . . The correct technology output to use is output The probability that a randomly selected person will score 449 or less is %.
