Please do this on MS EXCEL. Please show the step by step process on EXCEL. So I can use it as a guide. Thank you.


In replicate analyses, the carbohydrate content of a glycoprotein ( a protein with sugars attached to it) is found to be 12.6, 11.9, 13.0, 12.7, and 12.5 g of carbohydrate per 100 g of protein.
