Hi all!
I have an exam tomorrow and one of the sample questions I have been given is...
The weights of apples in an orchard are normally distributed with mean = 120 grams and standard deviation = 9 grams.
What is the approximate probability that a random sample of 81 apples will weigh under 9000 grams?
I understand it until the second line that asks about the probability, if any one could provide me with a method/formula to solve this I'd really appreciate it. I have already Googled for about 2 hours with no results for a question worded like this. Thanks in advance! Jonny
