Assume you tested svereral Firestone tires and recorded their failure times (as defined by an engineer).

Assume you tested svereral Firestone tires and recorded their failure times (as defined by an engineer).After doing a Chi-Square test ,you decided taht failures are normally distributed ,with mean failure of 50,000 miles and a standard deviation of 10,000 miles .Determine the following:
a) reliability of the tires at 40,000 miles
b) given that a tire has been driven (on a test machine) 20,000 miles, determine its reliability at 60,000 miles.
