Find the t values that form the boundaries of the critical r

Find the t values that form the boundaries of the critical region for a two-tailed test with = 0.10 for each of the following df values. (Round your answers to three decimal places.)

(a)    df = 5
t = ±  

(b)    df = 16
t = ±  

(c)    df = 22
t = ±

Solution

a)
Critical Value
The Value of |t | with n-1 = 5 d.f at 10% LOS is 2.015

b)
Critical Value
The Value of |t | with n-1 = 16 d.f at 10% LOS is 1.746

c)
Critical Value
The Value of |t | with n-1 = 22 d.f at 10% LOS is 1.717
