Hi, i'm david and i'm mr.
00:02
Havdzianz in your question.
00:03
Now let me bring up your question here.
00:06
In the question here, we are going to discuss about the empirical rule for the normal.
00:12
Let me remind you that even the x follows by the normal, when the mean and the standard division, and then the empirical rule says that we have the probability of the x between the one standard division around the mean.
00:30
So the mean minus 1 sigma and the mean plus 1 sigma, it will be around 68%.
00:38
The probability of the x between the mule minus 2 standard division, mu plus 2 standard division, it will be around the 95%.
00:49
And the probability of the x between the mean minus 3 standard deviation, mew plus 3 standard division, it will be around the 99 .7%.
01:03
Now the question here, we are given the x.
01:06
It will be followed by the normal when the mean equal to the 289 .6.
01:16
This will be the point...
