The Tesla Model X is an electric car that can travel approximately 238-295 mi on a full charge. Tesla dealers claim the time it takes to fully recharge depends on the percent depleted, but is approximately a normal random variable X with mean u = 2.5 hours and standard deviation o = 0.75 hour (on a 240-volt line). Suppose a random Tesla Model X is connected to a home recharging station. (c) If the amount of time to fully recharge...
