34 packages are randomly selected from packages received by a parcel service. The sample has a mean weight of 25.9 pounds and a standard deviation of 3.8 pounds. What is the 95% confidence interval for the true mean weight, μ, of all packages received by the parcel service?
24.6 < μ < 27.2
24.8 < μ < 27.0
24.2 < μ < 27.6
24.4 < μ < 27.4
