Hello, here we have to answer questions 3 and 4 only.
00:04
Let's do this.
00:06
In question 3, we have to find the upper and lower outliers boundary.
00:21
To answer this question, we first need to know the mean.
00:24
And here the mean is 6 .5.
00:27
We need to know q1, the first quantile, that is 2.
00:31
And we also need to know the q3, the third quartile.
00:39
In this specific case, this is 20.
00:42
Then we have to calculate the difference between 20 and 2, that is 18.
00:48
And let's determine the lower outlier boundary.
00:54
Let's calculate it.
01:09
Actually, let me correct myself.
01:11
So we need to know the median, not the mean.
01:15
So here lower outlier boundary is q1 minus 1 .5 times 18...
