What is the t value for a 20% two-tailed test with degrees of freedom = 9
I do not just want an answer. I want to know step by step how to get the answer
------------
To get the answer you need a T-chart or a calculator that generates t-values,
such as a TI-84.
-------
Since the test is 2 tail, each tail has 10%
Check your T-chart for df=9 and left (or right) tail = 0.1000
---
Using a TI I get invT(0.9,9) = 1.3830
