What are the critical values oftfor each of the following values ofNand alpha using a nondirectional hypothesis?

a. N =12 a=0.05

b. N=20 a=0.01

c. N=2 a=0.05

d. N=5 a=0.02

e. N=19 a=0.01

Now using a directional hypothesis?

f. N=13 a=0.025

g. N=17 a=0.005

h. N=8 a=0.05

i. N=15 a=0.01

j. N=10 a=0.05
