For the following hypothesis test, where H0: μ ≤ 10; vs. HA: μ > 10, we reject H0 at level of significance α and conclude that the true mean is greater than 10, when the true mean is really 14. Based on this information, we can state that we have: Made a Type I error. Made a Type II error. Made a correct decision. Increased the power of the test.
