Assuming 18 .4 % is the true percentage of people who thought oj simpson was innocent prior to jury selection.
00:10
10 jurors were randomly and independently selected from the population.
00:16
I'm going to let x be the number of jurors out of these 10 who believe in simpson's innocent prior to jury selection.
00:24
Now x follows the binomial distribution.
00:26
You can see there are four criteria.
00:29
The first criteria, the number of trials end is fixed and are identical.
00:32
Since there are 10 jurors, there will be 10 trials, so n is equal to 10.
00:38
In each of this trial, we take a look at a juror from this sample and see whether he or she believes in simpson's innocent prior to jury selection.
00:47
So all the 10 trials are identical.
00:50
Hence the first criteria is fulfilled.
00:52
His second criteria is trial is independent.
00:55
Now whether a juror believes in his innocent prior to jury selection or not is independent from the other jurors.
01:03
So the second criteria is fulfilled.
01:06
The criteria is trial results involved to outcome, success and failure.
01:10
A success will be a true role, believes in simpson's innocent prior to jury selection, and failure would be this person does not believe in simpson's innocence prior to jury selection...
