Question 1180151: Suppose the scores in statistics exam are normally distributed. If the exam has a mean score of 25 and a standard deviation of 5,what is the probability that if you take the exam you will get a score higher than 32, points? Answer by ewatrrr(24785) (Show Source):
Hi
Normal Distribution: µ = 25 and σ = 5
Using TI or similarly an inexpensive calculator like a Casio fx-115 ES plus
Continuous curve
Select ONE
P(x > 32) = P(x ≥ 32) = normalcdf(32, 9999, 25, 5) = .0808
