To discover the T basic incentive on a TI-84 mini-computer, we can utilize the accompanying capacity:

invT(probability, v)

where:

likelihood: the criticalness level

v: the degrees of opportunity

You can get to this capacity on a TI-84 adding machine by squeezing second and afterward squeezing vars. This will take you to a DISTR screen where you would then be able to utilize invT():
