Question

For a t distribution with 16 degrees of freedom, find the area (probability) in each region (do not round your answers):

To the right of 2.120

To the left of 1.337

To the left of -1.746

To the right of 2.583

Between -2.120 and 2.120

Between -1.746 and 1.746

Answer 1

Solution :

Using t ,

To the right of 2.120

P(t₁₆ > 2.120) = 0.05

Area = 0.05

To the left of 1.337

Area = 0.9

To the left of -1.746

Area = 0.05

To the right of 2.583

Area = 0.01

Between -2.120 and 2.120

Area = 0.95

Between -1.746 and 1.746

Area = 0.9
