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?
Homework Answers
Answer)
Yes in normal distribution
Mean = mode = median
All are equal
So mean = mode = median = 550
