Web$\begingroup$ For a two tailed test, you're looking for the probability that the value is less than -11.244 or more than +11.244. lower=F tells R to compute the probability of the value being more than the first parameter. Otherwise, it gives you the probability of the value being less than the first parameter. As such, you could also do 2*pt(-11.244, 30).
