Problem: Suppose that a tire manufacturer believes that the lifetimes of its tires follow a normal distribution with mean 48,000 miles and standard deviation 5,000 miles. Hint: Use the normal probability calculator were applicable. Questions: 1) Determine the probability that a randomly selected tires lasts for less than 40,000 miles. Round your answer to three decimal places 2) Determine the probability that a randomly selected tire lasts for more than 55,000 miles. Round your answer to three decimal places. 3) If the manufacturer wants to issue a guarantee so that 99% of its tires last for longer than the guaranteed lifetime, how many miles should it advertise as its guaranteed lifetime? Round number of miles to the nearest mile
