The square root of 9 is 3
Eq= y=k/x( if y is inversely prop to x)

Answer: 50,000 miles.
Step-by-step explanation:
We know that the sample mean is the best point- estimate of the population mean .
Given : In sample of 100 newly developed automobile tires, the average tread wear was found to be 50,000 miles and with a standard deviation of 3,500 miles.
i.e.
s=3,500 miles.
Then, the best estimate of the average tread life in miles for the population of these tires is 50,000 miles.
