An automobile company is looking for fuel additives that might increase gas mileage. Without additives 17 their cars are known to average 17 mpg (miles per gallons)with a standard deviation of mpg on 6 a road trip from Muscatto Sur. The company now asks whether a new additive increases this value. In a study, forty cars are sent on a road trip from Muscat to Sur. Suppose it turns out that the forty cars average x - (17 + 0.75)mpg with the additive.Can we conclude from this result that the additive is effective? a. With a significance level of 5%. b. With a significance level of 1%
