Step 1

It is given that T follows a t distribution with degree of freedom. Here we need to find t_{0} such that

P(|T|<t0) = 0.9

Step 2

here we need to find t_{0} such that P(|T|<t_{0}) = 0.9. This means that there exists t_{0} sucht that from -t_{0}_{ }_{ }to t_{0}_{ }the distribution has an area of 0.9 as shown in below diagram.

As we know the T distirbution is symmetric we know the area to the right of t_{0} is half of reamaining area which half of 0.1. So it is 0.05 as shown in the diagram.

Step 3

P(-t0 < T < t0 ) = 0.9
