The commands pt and qt compute probabilities and quantiles (or percentiles) of the t distribution. To compute the probability that A t random variable with 4 degrees of freedom is below 2.31, use
To compute the 75-th percentile of the t distribution with 7 degrees of freedom, i.e. qthe value t* such that a t random variable with 7 degrees of freedom has probability 0.75 of being below t*, use
