Hi, i'm david and i'm here to help you answer your question.
00:04
Now let me bring up your question here.
00:06
In the question here, we are going to discuss about the t distribution.
00:11
Now we're going to compute the probability with the t distribution.
00:15
The question i asked to find the probability of the t -17 degree freedom smaller than equal to the 1 .64.
00:26
And to find this value, i need to use the distribution, the calculator.
00:31
So let me use the calculator with the 17 degree freedom.
00:39
The t here equals to the 1 .64.
00:49
And then we get the value equal to the 0 .9.
00:54
I need to round to the 363 decimal places, we mean the 0 .903.
01:00
And for the question b, i need to find the two values minus c and c so start the probability of the t will be equal to the 0 .95.

This one, it will try to express it as the graph...
