For a t-curve with df = 8, find each t-value, and illustrate your results graphically.

a. The t-value having area 0.05 to its right

b. t 0.10

c. The t-value having area 0.01 to its left (Hint: A t-curve is symmetric about 0.)

d. The two t-values that divide the area under the curve into a middle 0.95 area and two outside 0.025 areas
