Question 1021692: is this a normal distribution or sampling distribution question? and then how do you solve it?
The state of California has a mean annual rainfall of 27.6 inches, whereas the state of New York has a mean annual rainfall of 48.7 inches. Assume the standard deviation for California is 4.9 inches and for New York is 3.1 inches. Find the probability that, for a sample of 35 years of rainfall for California, the mean annual rainfall is at least 29 inches. (answer rounded 4 decimal places)
p(z=>29inches) Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! It is the usual normal distribution problem, but the r.v. X is the sample mean.
==>
Now use your usual standard normal distribution table and scientific calculator to find the probability.
