There is given a normal distribution for this question.
00:03
The mean and the standard division was given here.
00:05
So the mean, which is denoted by meh, that was given as 104.
00:10
And the standard deviation, which is denoted by sigma, that was given as 14 here.
00:16
Since this is the normal distribution, i can define the random variable x, which is 104, the mean and the standard division, 14.
00:23
So we need to get the value of x is greater than 120.
00:27
In order to get this probability, i'm going to use the graphing display calculator application, which is normal cdf.
00:33
So the lower boundary is 120, and there is no in an upper boundary...
