00:00:00.540 --> 00:00:03.700 A:middle L:90%
All right. So this question wants us to develop
2
00:00:03.700 --> 00:00:08.099 A:middle L:90%
a point estimate for a survey of 150 people where
3
00:00:08.099 --> 00:00:11.220 A:middle L:90%
75 answered Yes, 55 Answer. No, and
4
00:00:11.220 --> 00:00:19.690 A:middle L:90%
25 gave no response. So part eh wants us
5
00:00:19.690 --> 00:00:23.170 A:middle L:90%
to find the point estimate for the proportion of successes
6
00:00:23.170 --> 00:00:27.949 A:middle L:90%
in the population. So we're looking for P hat
7
00:00:28.440 --> 00:00:30.949 A:middle L:90%
or P bar, depending on what you say.
8
00:00:31.739 --> 00:00:41.649 A:middle L:90%
Which equals number of yeses over number of Total,
9
00:00:43.640 --> 00:00:48.759 A:middle L:90%
which in this case, there's 75 yeses and there's
10
00:00:48.759 --> 00:00:52.670 A:middle L:90%
150 people total, which gives us a P hat
11
00:00:52.670 --> 00:01:03.840 A:middle L:90%
value off 0.5. Then Part B wants the sample
12
00:01:03.840 --> 00:01:08.450 A:middle L:90%
proportion of failures or no responses. So this time
13
00:01:10.739 --> 00:01:15.250 A:middle L:90%
we're looking for Q hat, which is equal to
14
00:01:15.040 --> 00:01:26.030 A:middle L:90%
the number of no response over the total. And
15
00:01:26.040 --> 00:01:30.750 A:middle L:90%
if we look, there were 55 no responses over
16
00:01:32.189 --> 00:01:36.489 A:middle L:90%
150 total, and that works out to be a
17
00:01:36.500 --> 00:01:44.459 A:middle L:90%
0.3667 And remember
