Suppose a New Engine Additive Is Designed to Improve Performance

question 21

Multiple Choice

Suppose a new engine additive is designed to improve performance in race cars and researchers wish to test the effectiveness of the new additive. On a closed race course, the individual race times for forty race cars are recorded. The race times (on the same course) for each of the cars after being treated with the engine additive are then recorded. Which test design would be most appropriate for this scenario?

• A)Paired t- test
• B)Two- sample t- test
• C)None of these
