The tread life of tires mounted on light duty trucks follows the normal probability distribution with a mean of 60,000 miles and a standard deviation of 4,000 miles. suppose you bought a set of four tires, what is the likelihood the mean tire life of these four tires is more than 66,000 miles?

 0.0013

Step-by-step explanation:

Given : The test scores are normally distributed with

Mean :

Standard deviation :

Sample size :

The formula to calculate the z-score :-

For x = 66,000

The p-value =

Hence, the likelihood the mean tire life of these four tires is more than 66,000 miles = 0.0013
