Two different chemical formulations of rocket fuel are considered for the peak thrust they deliver in a particular design for a rocket engine. The thrust/weight ratios (in kilograms force per gram) for each of the two fuels are measured several times. The results are as follows: Fuel A 54.1 52.9 57.9 58.2 53.4 51.4 56.8 55.9 57.9 56.8 58.4 52.9 55.5 51.3 51.8 53.3 Fuel B 55.1 55.5 53.1 50.5 49.7 50.1 52.4 54.4 54.1 55.6 56.1 54.8 48.4 48.3 55.5 54.7 A.Find the P-value. B.Can you conclude at the 5% level that the switch to fuel A should be made?

Question
Two different chemical formulations of rocket fuel are considered for the peak thrust they deliver in a particular design for a rocket engine. The thrust/weight ratios (in kilograms force per gram) for each of the two fuels are measured several times. The results are as follows:
| Fuel A | 54.1 | 52.9 | 57.9 | 58.2 | 53.4 | 51.4 |
| 56.8 | 55.9 | 57.9 | 56.8 | 58.4 | 52.9 | |
| 55.5 | 51.3 | 51.8 | 53.3 |
| Fuel B | 55.1 | 55.5 | 53.1 | 50.5 | 49.7 | 50.1 |
| 52.4 | 54.4 | 54.1 | 55.6 | 56.1 | 54.8 | |
| 48.4 | 48.3 | 55.5 | 54.7 |
A.Find the P-value.
B.Can you conclude at the 5% level that the switch to fuel A should be made?
