This refers to an intelligent guess about a population parameter.

• Decision

• Hypothesis

• Rejection

• Significance

It is the starting point of the investigation in hypothesis testing.

• Alpha Level

• Rejection Region

• Null Hypothesis

• Alternative Hypothesis

The calculations in determining rejection region can be graphically represented by using _____________.

• Bar Graph

• Straight Line

• Normal Curve

• Cartesian Plane

It is called the critical Region

• P (type II error) = ß

• Ho = parameter = specific value Ha = parameter < specific value

• Rejection region

• Ho = parameter = specific value Ha = parameter ≠ specific value

This is a two-tailed test

• P (type II error) = ß

• Ho = parameter = specific value Ha = parameter < specific value

• Rejection region

• Ho = parameter = specific value Ha = parameter ≠ specific value

This is a left-tailed test

• P (type II error) = ß

• Ho = parameter = specific value Ha = parameter < specific value

• Rejection region

• Ho = parameter = specific value Ha = parameter ≠ specific value
