Hi, i'm david and i'm here to help you answering your question.
00:03
Now let me bring up your question here.
00:06
In this question here, we are going to discuss about the standard normal distribution.
00:11
And to answer this question, i'm going to use the z table.
00:15
So let me copy the z table and i put it on the right here for you.
00:21
Now notice that the standard table i bring here, it has the negative g score with the probability on the left tail.
00:28
Here i want to find the value of the c, such as you.
00:30
So that z between the minus c and the c, it will equal to this value.
00:36
So we can express this probability is the area under the standard normal curve.
00:43
Now we have the middle one being the zero.
00:45
We need to find the minus c and the c such that the area in the middle.
00:52
It will equal to the 0 .9 -676...
