00:00:01.110 --> 00:00:03.229 A:middle L:90%
this question gives you a list of numbers and asks
2
00:00:03.229 --> 00:00:05.889 A:middle L:90%
you to find the mean the numbers that it gives
3
00:00:06.230 --> 00:00:18.030 A:middle L:90%
our 67 89 75 86 100 in 93. Now
4
00:00:18.030 --> 00:00:21.100 A:middle L:90%
we know that the mean or X bar is found
5
00:00:21.100 --> 00:00:24.510 A:middle L:90%
by adding all of the exes up. It's the
6
00:00:24.510 --> 00:00:29.500 A:middle L:90%
sum of excise over the number of data points that
7
00:00:29.500 --> 00:00:33.329 A:middle L:90%
is in here. We can clearly see that we
8
00:00:33.329 --> 00:00:36.469 A:middle L:90%
have six data points and equal six. And if
9
00:00:36.469 --> 00:00:38.770 A:middle L:90%
we plug all of these into our calculator, we
10
00:00:38.770 --> 00:00:41.409 A:middle L:90%
confined that. The sum of all the exes is
11
00:00:41.409 --> 00:00:46.039 A:middle L:90%
equal to 510. So x bar is just gonna
12
00:00:46.049 --> 00:00:49.509 A:middle L:90%
be equal to 510 divided by six, which is
13
00:00:49.509 --> 00:00:52.789 A:middle L:90%
simply 85 and that's your final.
