Question

For a t distribution with 16 degrees of freedom, find the area, or probability, in each region.

Answer 1

Answer:

We are given the t distribution with 16 degrees of freedom.

We have to find the area a. to the right of 2.120

Answer: We can use excel to find the area to the right of 2.120. The excel function is:

=TDIST(2.120,16,1) = 0.025

Therefore, the area to the right of 2.120 is 0.025

b. to the left of 1.337.

Answer: We can use excel to find the area to the left of 1.337. The excel function is:

=1 - TDIST(1.337,16,1) = 0.900

Therefore, the area to the left of 1.337 is 0.900
