S. The tread life a certain brand of tires is known to be normally distributed with a mean of 50,000 miles and a standard deviation of 4,500 miles a) Determine the probability that a randomly selected tire will last longer than 62,000 miles ANSWER b) The company wishes to set the warranty so that warranty mileage be? only 3% of the tires will need to be replaced, what should the ANSWER
The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 2000 miles
The tread life of a particular brand of tire is a random variable best described by a normal distribution with a mean of 60,000 miles and a standard deviation of 2000 miles. What is the probability a certain tire of this brand will last between 55,800 miles and 56,400 miles?

8. Tires become illegal when their tread depths fall below a certain value. A particular brand and model of tire has lifespans (number of miles that can be driven before they become illegal) that are approximately normal in distribution with mean 34,000 miles and standard deviation 3,800 miles. Use this information (and tables as needed) to answer parts a-c below. a) Determine the probability that a single tire, selected at random, has a lifespan of between 30,000 and 40,000 miles....
The mileage that car owners get with a certain kind of radial tire is normally distributed...
The mileage that car owners get with a certain kind of radial tire is normally distributed with a mean of 70,000 miles. If 97.725% of these tires lasted less than 78,000 miles, please calculate the standard deviation for the tire mileage. [Note: Please round your result for the standard deviation to the nearest integer.] [2 points] What is the probability a randomly selected tire of this type will last 65,000 miles? Please justify your answer. [1 point] Calculate the probability...
