SAT scores have approximately a normal distribution with mean equal to 550 and a standard deviation equal to 90. a) draw a graph of this distribution b) find the median and the mode -I drew the a normal bell graph with the middle number being the mean (550) and then added and subtracted 90 from each number for 3 standard deviations. Would the median and mode just be 550 as well since this a normal distribution?
