Question:
Self-driving vehicles periodically suffer from a disengagement of the self-driving feature. In these cases, it is important to know how long it takes for the driver to manually take control of the vehicle. In a study of 487 instances where a self-driving vehicle became disengaged from the selfdriving feature, the meantime for the driver to take control was 0.84 second with a standard deviation of 0.90 second.
(a) An analysis of the reaction times indicates that reaction time to disengagement is highly skewed right. Explain why a large sample size would be necessary to construct a confidence interval for the mean reaction time.
(b) Construct and interpret a 90% confidence interval for the mean reaction time to disengagement.

Professional, Experienced, and Expert tutor who will provide speedy and to-the-point solutions.
Hi there! Are you looking for a committed, reliable, and enthusiastic tutor? Well, teaching and learning are more of a second nature to me, having been raised by parents who are both teachers. I have done plenty of studying and lots of learning on many exciting and challenging topics. All these experiences have influenced my decision to take on the teaching role in various capacities. As a tutor, I am looking forward to getting to understand your needs and helping you achieve your academic goals. I'm highly flexible and contactable. I am available to work on short notice since I only prefer to work with very small and select groups of students.
I have been teaching students for 5 years now in different subjects and it's truly been one of the most rewarding experiences of my life. I have also done one-to-one tutoring with 100+ students and helped them achieve great subject knowledge.
