I think I may have found a typo in a statistics problem.  It doesn't affect the correct answer, but it might be confusing, and the correction is straight forward.  Assuming, of course, I have not made an error.  In that case, my sincere apologies.

This typo is found in the Significance Tests unit, Practice Quiz: Making conclusions in a t test for a mean. The problem begins, "A quality control engineer is testing the battery life of a new smartphone."  The problem states a given p-value and a given alpha.  Just for fun, I attempted to use the background info to confirm the givens, and the four background data do not yield the given p-value. I think the simplest correction is changing n from 50 to 30, then all will be consistent.

Thanks for considering, and keep up the good work on this site.  I have spent countless fruitful hours here and frankly I am amazed that this is the very first issue I have found.  This is a testament to how good this site is!
