Question

Find the t-value with 0.20 area to its left and df = 30.

Answer 1

Given:

Area = 0.20 to its left.

Degrees of freedom, df = 30

Let's find the t-value.

To find the t-value, let's use the t-value table.

We have:

$t_{\frac{\alpha}{2},df}=t_{0.20,30}=-0.854$

Therefore, the t-value is -0.854.

• ANSWER:

-0.854
