So to check if the distribution that they saw for the cops here or police officers is the same as the distribution that we have of like people under 18 in new york city.
00:19
First for the under 18, so i'm gonna put here, we have the following group or percentages.
00:30
So we have like white, black, latino, asian and other.
00:36
So for white we have 29 .2, then we have 28 .2, then 31 .5, 9 .1, and 2%.
00:49
For the values that they got in terms of police officers, and this was based in a sample of here, 26 ,181, which i can even put that is the total number of police officers.
01:07
So for white we have a 64 .8, black 14 .5, 19 .1 and 1 .4, which means that we have 0 here for others.
01:24
So in this case, to test this, because we want to see if these two distributions are the same or not, we can use the chi -square test here for the, in this case, for equal distribution.
01:45
So to test if they have the same, we could use a software here...
