3. You are in charge of a delivery company that has a large fleet of delivery truck. The distance a truck travels in a day follows unknown distribution with an unknown mean/expectation μ and variance σ^2 . We take a sample of n=36 trucks, and compute ̄X = 55 (sample mean) and s^2 = 49 (thqe sample variance). a. Create a 95% confidence interval for μ. b. Create a 99% confidence interval for μ.
