Hi, i'm david and i'm here to help you answer your question.
00:03
Now let me bring up your question here.
00:06
In the question here we're going to discuss about the normal distribution.
00:10
Let me remind you that if we have the x that follows by the normal, when the mean and the standard division, then we turn the x minus the mean of a standard division.
00:20
We obtain the standard normal.
00:22
In the question here, we're given the graph on the standard normal and the middle value will be the mean equal to the 52, and the division equal to the 20.
00:35
And the value 36 will be somewhere on the left, 36 here.
00:40
And we need to find the area on the right of the 36.
00:45
Now that's area there can be written down as a probability of the x.
00:50
It will be greater than the 36...
