T tests, degrees of freedom and proportions?
what proportion of scores would fall in each of these areas (and what formula did you use to find them please)

a) df= 25, below t=2.485
b) df=10,000, between t=-1.25 and t=2.75
c) df=1, above t=+31.821, below t=-31821
d) df=10, between the mean and t=+1.812
e) for df=21, t above 0

please help me understand this crazy talk thank you!
