Module 2 Application Activity - RocktSci - Chapter 6 I. RocktSci uses two main ingredients to make rocket fuel used to power rocket engines for space missions. They are ammonium perchlorate powder (the oxidizer), and fine aluminum powder (the fuel), held together by a binder of petroleum-based rubber with the acronyms PBAN or HTPB. The company wishes to test the fuel mixtures in a prototype engine (treatments) with a high and a low level of ammonium perchlorate and a high and low level of aluminum powder. RocktSci wishes to set up a 2 X 2 experimental design to determine which is the ideal combination of high and low ingredients to produce the maximum thrust level. Use the thrust data below and the spreadsheet template supplied to interpret the results and make a recommendation to management. RocktSci, Inc.
