WebThe Excel T function converts numbers, dates, and the logical values TRUE and FALSE into empty strings . Text values and errors are not converted and pass through unaffected. You can use the T function to remove values that are not text. The T function takes one argument, value, which can be a cell reference, a formula result, or a hardcoded value. 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).
