A factory produces car tires. The number of miles each tire lasts before it completely wares out follows a normal distribution w

qwelly [4]

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 : $\dfrac{x-\mu}{\sigma}$

For x= 62,000

$z=\dfrac{62000-50000}{8000}=1.5$

By using the standard z-value table , the probability for a randomly selected tire to last for at least 62,000 miles will be :_

$P(x\geq62000)=P(z\geq1.5)=1-P(z$

Hence, the probability for a randomly selected tire to last for at least 62,000 miles = 0.0668073
