The company wishes to use a new steel supplier and have asked the quality department to carry out an assessment. They need to know if the new steel gives better results than the old steel on certain operations. I have assumed that a t test is to be used. I say assumed, because I have been thrown in at the deep end on this one and am struggling a bit. Now, I have the results of the t test done in Excel, but, I have no idea what the figures really point to. I would be grateful if some kind soul could explain the results to me. And, is the t test the appropriate test to use?
