00:00:01.040 --> 00:00:05.230 A:middle L:90%
Okay, let's look at question 14 together here.
2
00:00:06.940 --> 00:00:12.439 A:middle L:90%
So, um, our no hypothesis ISS The median
3
00:00:12.439 --> 00:00:19.780 A:middle L:90%
is equal to 83,000 and two under 82. And
4
00:00:19.780 --> 00:00:24.030 A:middle L:90%
the alternative hypothesis is that the media and is smaller
5
00:00:24.030 --> 00:00:32.240 A:middle L:90%
than this amount of money. Um, because here
6
00:00:32.240 --> 00:00:36.149 A:middle L:90%
, the sign is smaller than so, which means
7
00:00:36.149 --> 00:00:43.140 A:middle L:90%
we're looking at the one talk situation. All right
8
00:00:43.149 --> 00:00:46.689 A:middle L:90%
, um, by looking at the table list at
9
00:00:46.689 --> 00:00:49.770 A:middle L:90%
the low, we know that the sample size is
10
00:00:49.770 --> 00:00:55.750 A:middle L:90%
20. And, uh, and off Linus is
11
00:00:55.750 --> 00:01:00.820 A:middle L:90%
16 and off, plus is four. So our
12
00:01:00.829 --> 00:01:08.489 A:middle L:90%
X star that is going to be, um,
13
00:01:08.500 --> 00:01:12.260 A:middle L:90%
is going to be four, cause for a smaller
14
00:01:12.260 --> 00:01:18.239 A:middle L:90%
than 16. All right, um, So what
15
00:01:18.239 --> 00:01:19.750 A:middle L:90%
we're going to do right now is that we're going
16
00:01:19.750 --> 00:01:26.769 A:middle L:90%
to look at table 12 and find the corresponding line
17
00:01:26.769 --> 00:01:32.569 A:middle L:90%
for Enos. He go to 20 so Oh,
18
00:01:32.579 --> 00:01:42.569 A:middle L:90%
just try here. Can the above, Because their
19
00:01:42.569 --> 00:01:46.709 A:middle L:90%
own point. There are one narrow mind. No
20
00:01:46.819 --> 00:01:53.959 A:middle L:90%
, by their white one 0.2 by and we have
21
00:01:53.959 --> 00:02:00.459 A:middle L:90%
three high by six and know that here are Crippen
22
00:02:01.540 --> 00:02:07.310 A:middle L:90%
. Our X star is four. So four is
23
00:02:07.310 --> 00:02:12.719 A:middle L:90%
in between three and five. So which means our
24
00:02:12.729 --> 00:02:22.650 A:middle L:90%
P value should be tweeting between their open, their
25
00:02:22.650 --> 00:02:28.449 A:middle L:90%
one divided by two here and smaller than their opine
26
00:02:28.460 --> 00:02:30.800 A:middle L:90%
. There are five D bye bye to the result
27
00:02:30.810 --> 00:02:35.610 A:middle L:90%
women to divide by two year. Because instead of
28
00:02:35.610 --> 00:02:38.449 A:middle L:90%
looking at to tell situation, we're actually looking at
29
00:02:38.449 --> 00:02:43.259 A:middle L:90%
one type situation. So we need Teoh, um
30
00:02:43.259 --> 00:02:47.699 A:middle L:90%
, divided by two and which is going to be
31
00:02:51.240 --> 00:02:55.599 A:middle L:90%
, um, people greater than their A 0.5 and
32
00:02:55.599 --> 00:03:01.699 A:middle L:90%
smaller than the aeroplane. There are 25 And from
33
00:03:01.699 --> 00:03:07.430 A:middle L:90%
the question we know that the ec Tropea Vallo calculated
34
00:03:07.430 --> 00:03:13.370 A:middle L:90%
by the computer is Geico to their A pine.
35
00:03:13.379 --> 00:03:19.289 A:middle L:90%
There are there, 05 night and is in between
36
00:03:19.460 --> 00:03:23.449 A:middle L:90%
the pounds. We just find out. So,
37
00:03:23.009 --> A:middle L:90%
um
