Answer: 0.0668073
Step-by-step explanation:
Given : The number of miles each tire lasts before it completely wares out follows a normal distribution with mean μ = 50,000 miles and standard deviation σ = 8,000 miles.
Let x be the random variable that represents the number of miles each tire lasts.
z-score :
For x= 62,000
By using the standard z-value table , the probability for a randomly selected tire to last for at least 62,000 miles will be :_
Hence, the probability for a randomly selected tire to last for at least 62,000 miles = 0.0668073
