Asked by rachel

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

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).
