Normat/t-distribution Probabilities

Test Distribution: Normal Distribution t-Distribution with degrees of freedom

Mean:
Standard deviation:

Probability to calculate:
P(x<)
P(x>)
P(<x<)
P(x<??)=
P(x>??)=

Image Size: Width= Height=

Note: This creates the graph based on the shape of the normal curve, which is a reasonable approximation to the t-distribution for a large sample size. The probabilities are accurate, but the graphs are not accurate if you are doing a t-distribution with small sample size (less than 30).
