A car battery has an average lifetime of 48 months with a standard deviation of 6
Chapter 5, Problem 139(choose chapter or problem)
Probability A car battery has an average lifetime of 48 months with a standard deviation of 6 months. The battery lives are normally distributed. The probability that a given battery will last between 48 months and 60 months is \(0.0665\ \int_{48}^{60}\ e^{-0.0139(t-48)^2}\ dt\). Use the integration capabilities of a graphing utility to approximate the integral. Interpret the resulting probability.
