As a construction engineer for a city, you are responsible for ensuring that the company that is providing gravel for a new road puts as much gravel in each truckload as they claim to. It has been estimated that it will take 500 truckloads of gravel to complete this road, so you plan to measure the volume of gravel in an SRS of 25 trucks to make sure that the company isn’t delivering less gravel per truckload than they claim. Each truckload is supposed to have 20 m³of gravel, so you will test the hypothesis H₀: μ = 20 versus H_a: μ < 20. Describe what a Type I error is in this context.
