A car manufacturer is analyzing the fuel efficiency of its latest models. The company wants to determine whether there is a significant difference in the mean fuel efficiency between its two most popular models, Model A and Model B. A sample of 30 cars of Model A was tested, and the mean fuel efficiency was 30 miles per gallon with a standard deviation of 3 miles per gallon. Another sample of 35 cars of Model B was tested, and the mean fuel efficiency was 28 miles per gallon with a standard deviation of 4 miles per gallon. Conduct a hypothesis test with a 1% significance level to determine whether there is a significant difference in the mean fuel efficiency between Model A and Model B.
