Hi. This question would be laughed toe to find
2
00:00:03.960 --> 00:00:08.470 A:middle L:90%
Chi square and justice is six for two different samples
3
00:00:08.539 --> 00:00:12.650 A:middle L:90%
. So for the 1st 1 I used many tab
4
00:00:12.789 --> 00:00:19.420 A:middle L:90%
on. I found that guys square is equal to
5
00:00:19.420 --> 00:00:24.850 A:middle L:90%
seven point 16 degree. Freedom is nine because the
6
00:00:24.859 --> 00:00:31.879 A:middle L:90%
real freedom is equal and minus one, and evil
7
00:00:31.890 --> 00:00:38.450 A:middle L:90%
is 1758 on when we change the sample to 20
8
00:00:40.439 --> 00:00:44.759 A:middle L:90%
we found that. So the statistics is the team
9
00:00:44.759 --> 00:00:53.049 A:middle L:90%
board 96 So and increases okay on the P value
10
00:00:54.539 --> 00:00:58.270 A:middle L:90%
, it becomes now going forth to eight. So
11
00:00:58.280 --> 00:01:02.509 A:middle L:90%
it decrease and that's actually take care of part C
12
00:01:02.640 --> 00:01:04.560 A:middle L:90%
and the So what will have been for that?
13
00:01:04.560 --> 00:01:08.140 A:middle L:90%
This is a six, as is gonna increase because
14
00:01:08.140 --> 00:01:12.349 A:middle L:90%
, as you know, from the formula, it
15
00:01:12.349 --> 00:01:19.390 A:middle L:90%
is and minus one here, this where with us
16
00:01:19.390 --> 00:01:26.790 A:middle L:90%
in the square. So I'm assuming this part this
17
00:01:26.790 --> 00:01:32.060 A:middle L:90%
fixed constant in some sense. So when you're in
18
00:01:32.060 --> 00:01:36.810 A:middle L:90%
keys in Chi Square or the just statistics is gonna
19
00:01:36.810 --> 00:01:41.829 A:middle L:90%
increase, and that's gonna have a consequence, which
20
00:01:41.829 --> 00:01:46.359 A:middle L:90%
is we're gonna have ah better P values, which
21
00:01:46.359 --> 00:01:49.650 A:middle L:90%
is, um, less big value here
