Same, with the extra comment that every other math course I took had some way of verifying your result. You do your work and the result can be plugged into the original question to calculate some other element and see if it matches, or the value can be checked visually, or the equation will cancel out completely, or ... Not with the statistics as taught at the time. Your result is 0.48 - did you use the right test? was it supposed to be two tailed? did you calculate properly? did you choose the right distribution? does that method work with this distribution? Who knows. It's basically a memory exercise.
