Textbook Problem

Find the t values that form the boundaries of the critical region for a two-tailed test with α = .05 for each of the following sample sizes:

a. n = 6

b. n = 12

c. n = 24

a.

To determine

To find: The t-values that form the boundary of the critical region for a two-tailed test

Explanation

Given info:

A two-tailed test is conducted using α=0.05 for a sample of size 6.

Calculation:

A sample of n=6, the t-statistics will have (n1) degrees of freedom, i.e. df=5

b.

To determine

To find: The t-values that form the boundary of the critical region in the right-hand tail for a two-tailed test.

c.

To determine

To find: The t-values that form the boundary of the critical regionin the right-hand tail for a two-tailed test
