So based on your symbols, hopefully i'm going to answer your question correctly.
00:05
So you have a t distribution with 13 degrees of freedom.
00:09
And you want to know what is the probability that i believe you want that the t value is.
00:15
And i'm going to assume you mean greater than or equal to 1 .71.
00:18
So if i draw the little picture here, here's the t value of 0.
00:22
Here's a 1.
00:24
Here's a 2.
00:25
The 1 .71 is about here.
00:27
Now i'm going to find that answer by using my t cdf.
00:31
And i'm going to put in 1 .71.
00:34
And then a very big number.
00:38
And then 13 degrees of freedom.
00:41
Because my table will not give me but between certain values.
00:46
And using my software, that tells me that the probability is, and you want it to at least three decimal places...
