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 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...

The lifetime of a certain brand of tires is approximately normally distributed, with a mean of 45,000 miles and a standard deviation of 2,500 miles. The tires carry a warranty for 40,000 miles.(Show work please) What proportion of the tires will fail before the warranty period? What proportion of the tires will fail after the warranty expires, but before they have lasted for 41,000 miles? Suppose a sample of 100 randomly selected tires are tested, what is the probability that...
