A supermarket receives a shipment of 1000 boxes of apples (each of which holds 10 apples). The following numbers of boxes have 0,1,2,3,4...
10 rotten apples.

0 -334
1 - 362
2 -191
3 - 63
4 - 22
5 - 12
6 - 9
7 - 0
8 -3
9 -2
10 - 2

Does the distribution of rotten apples follow a binomial distribution? Calculate all
needed parameters.


I say "yes" because there is a discrete number of trials, and they are independent, there are 2 outcomes, and each box has a 50/50 chance of being rotten or good.

Is this right?

Also, what are parameters? Is that mean and Std. Deviation?

You seem to have misunderstood the question. There are NOT "2 outcomes". The outcomes are the number of rotten apples in a box, not whether the box is "rotten or good".

Also, what are parameters? Is that mean and Std. Deviation?
Yes.
 
Oh, I see.

So if there was only 1 apple it would be a binomial distribution, correct?

The different possibilities exclude this from being a binomial distribution?
