A boat manufacturer claims that a particular boat and motor combination will burn less than 4.0 gallons of fuel per hour. Fuel consumption for a random sample of 10 similar boats resulted in the data below:
4.06, 4.29, 4.26, 4.64, 4.23, 3.93, 3.64, 4.13, 3.93, 3.86
Is there sufficient evidence to conclude that the manufacturer's claim is correct? Use α = .05 and test the appropriate hypothesis.
