Question

For a t distribution with 16 degrees of freedom, find the area, or probability, in each region. (Round your answers to three decimal places.)

a)to the right of 1.337
b)to the left of 1.746
c)to the left of −2.120
e)between −1.337 and 1.337

Answer 1

To find the area under the t-distribution curve, use a t-table or calculator.

Step-by-step explanation:

To find the area under the t-distribution curve, we need to use a t-table or a calculator. For a t-distribution with 16 degrees of freedom, the area to the right of 1.337 can be found by subtracting the area to the left from 1. Similarly, the area to the left of 1.746 can be found by using the t-table or calculator. To find the area to the left of -2.120, we can use the t-table or calculator. Finally, to find the area between -1.337 and 1.337, we can subtract the area to the left of -1.337 from the area to the left of 1.337.
