Tires have a normal distribution with a mean of 70000 miles and a standard deviation of 4400 miles. What proportion of tires wil

yarga [219]

Let T = the distance, in miles, a tire lasts

T ~ N(70000,4400<span>²</span>)

P(T $\geq$ 75000)
= P(Z $\geq \frac{75000 - 70000}{4400}$ )
= P(Z $\geq \frac{25}{22}$ )
≈ P(Z $\geq$ 1.14)
= 1 - P(Z < 1.14)
≈ 1 - 0.8729
= 0.1271
