Suppose that a device advertised to increase a car's gas mileage really does not work. We test it on a small fleet of cars (with H₀: not effective), and our data results in a P-value of 0.004. What probably happens as a result of our experiment?
◦ We fail to reject H₀, committing a Type II error.
◦ We correctly fail to reject H₀.
◦ We reject H₀, making a Type I error.
◦ We reject H₀, making a Type II error.
◦ We correctly reject H₀.
