A diesel engine company that is developing a new engine has concluded that the updated engine provides better fuel economy than the current engine.They made this decision using α = 0.01.Would they have made the same decision at α = 0.10 and α = 0.05?
Fuel Economy
Fuel economy refers to the efficiency of a vehicle in using fuel, typically expressed in miles per gallon (mpg) or liters per 100 kilometers (L/100km), indicating how far a vehicle can travel on a specific amount of fuel.
Diesel Engine
An internal combustion engine in which heat produced by the compression of air in the cylinder is used to ignite the fuel.
Alpha
A coefficient representing the level of significance in hypothesis testing, often set at 0.05 or 5%, indicating the probability of rejecting a true null hypothesis.
- Achieve comprehension and describe the significance of p-values in hypothesis testing scenarios.
- Grasp the criticality of error levels (α) in hypothesis testing and their implications for choices and decisions.

Final Answer :
α = 0.10 and 0.05: Yes.The P-value is < 0.01,so it's less than both 0.05 and 0.10.
