A normal distribution was given in this question.
00:04
So we know that the population mean, which is denoted by mu, this is 36 .9.
00:10
And the population standard deviation was also given here, denoted by sigma, which was given as 0 .4 celsius.
00:19
So let me define the random variable x for this normal distribution.
00:23
And the mean is 36 .9, and the standard deviation, 0 .4.
00:28
So we have to find the 76th percentile.
00:31
The 76th percentile is denoted by p76.
00:34
And let's say this is equal to x1.
00:36
So we have to find the value of x1 for this question.
00:39
First of all, let me draw the normal distribution...
