New to the site - I've managed 11 out of 13 questions for my final set of Master Black Belt homework but now stuck!

Can anyone offer an explanation to this question and how it could be answered in minitab? I've had a very extensive look online and found multiple solutions but cannot work out how they have got to the answer or how it could be done in minitab. I have to provide an explanation with the solution.

Thank you in advance - I would really like to try to get to grips with this one!

so that eight-ounce cups will overflow only 1% of the time.
