Harrizon [31]

Answer:

Tires that wear out by approximately 24307.8 miles will be replaces free of charge.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 27,000 miles

Standard Deviation, σ = 2100 miles

We are given that the distribution of life expectancy is a bell shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

We have to find the value of x such that the probability is 0.10

$P( X < x) = P( z < \displaystyle\frac{x - 27000}{2100})=0.10$

Calculation the value from standard normal z table, we have,

$\displaystyle\frac{x - 27000}{2100} = -1.282\\\\x = 24307.8$

Tires that wear out by approximately 24307.8 miles will be replaces free of charge.
