Question 9: give the hypotheses A company is designing a new electric to compete with a competitor. Thecompany wants their average battery to be better than the car out. Thecompany does not want to spend too much on the initial process so theyuse only 37 cars. The average battery range of the 37 cars is 401 mileswith a standard deviation of 50 miles. Since the other car is already inproduction, there is much more data on the battery range. The averagebattery range of 100 of the competitor's car is 400 miles with a standarddeviation of 8 miles. The battery range is normally distributed. At the 5%significance, determine if the average battery range of the new vehicle isbetter than the competitor. Take the new vehicle as population 1.Give the hypothesis.Null: There is no difference in the average battery range of the two vehicles.Alternative: The average battery range of the competitor is better.Null: There is no difference in the average battery range of the two vehicles.Alternative: The average battery range of the new vehicle is not equal to theaverage battery range of the competitor.Null: There is no difference in the average battery range of the two vehicles.Alternative: The average battery range of the new vehicle is better than thecompetitor.

Test is that whether the average battery range of the new vehicle is better than the competitor.
