A company is designing a new electric to compete with a competitor. The company wants their average battery to be better than the car out. The company does not want to spend too much on the initial process so they use only 37 cars. The average battery range of the 37 cars is 401 miles with a standard deviation of 50 miles. Since the other car is already in production, there is much more data on the battery range. The average battery range of 100 of the competitor's car is 400 miles with a standard deviation of 8 miles. The battery range is normally distributed. At the 5% significance, determine if the average battery range of the new vehicle is better 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 the average 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 the competitor.

Transcribed Image Text:A company is designing a new electric to compete with a competitor. The
company wants their average battery to be better than the car out. The
company does not want to spend too much on the initial process so they
use only 37 cars. The average battery range of the 37 cars is 401 miles
with a standard deviation of 50 miles. Since the other car is already in
production, there is much more data on the battery range. The average
battery range of 100 of the competitor's car is 400 miles with a standard
deviation of 8 miles. The battery range is normally distributed. At the 5%
significance, determine if the average battery range of the new vehicle is
better 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 the
average 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 the
competitor.
Transcribed Image Text:Give the conclusion.
Reject the null since the test statistic is not in the rejection region.
O Fail to reject the null since the test statistic is not in the rejection region.
