Describe the standard normal distribution. What are its characteristics? Choose the correct answer below. O A. The standard normal distribution is a normal probability distribution with mean u = 0 and standard deviation o = 1. Similar to any normal probability distribution, it has associated with it a bell-shaped curve, symmetric about a vertical line through u with inflection points at o and -o. The Z-scores theorem, along with a table of areas under this standard normal curve can be...

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?
