Question 465499: I'm stuck on this :/ some one please help
SAT verbal scores are normally distributed with a mean of 430 and a standard deviation of 120 If 1 of the student is randomly selected, find the probability that he or she obtained a score higher than 440.
You can put this solution on YOUR website! z=(440-430)/120=.083
The area under the normal curve above z=.083 is .467 the probability that he or she obtained a score higher than 440.
