After performing a z-test, this entity is accepted if the z-score is sufficiently low.
This entity's name reflects the fact that there is no difference between the unknown population parameter and a constant usually denoted theta. If a sample falls within the "critical region," then this entity is assumed to be not true. The power of tests of this statement can be improved if one uses a one-sided test rather than a two-sided test. When the level of significance is greater than the p value, this entity should be accepted, because if you reject, you're more likely to make a type-one error. After performing a z-test, this entity is accepted if the z-score is sufficiently low. For 10 points, name this statistical hypothesis that may be rejected in favor of the alternative one.
