Mileage tests were conducted on a randomly selected sample of 100 newly developed automobile tires. The results showed that the average tread life was 52,515 miles with a standard deviation of 3,550 miles. What is the best estimate of the average tread life in miles for the entire population of these tires?

52,515
3,550
(52,515/100)
(3,550/100)

52,515

Thank you!

To estimate the average tread life in miles for the entire population of these tires, we can use the sample mean as the best estimate. In this case, the sample mean is 52,515 miles.

So, the best estimate of the average tread life in miles for the entire population of these tires is 52,515 miles.
