Z = (score-mean)/SD
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability related to your Z score(s).
1)Let X have a normal distribution with mean 6 and standard deviation 3. a) What is the probability that X > 8.7
2)What is the probability that X<0?
3)What is the probability that |X-6| > 1.9 ?
I have got so far:
P(Z > 0.9) but I do not know where to go
from here!
Thank You
