The null hypothesis

• is the hypothesis to be tested

• uses an equal sign

• gets the benefit of the doubt

• all of these

A left-tailed (one-tailed) test uses this symbol in the alternative hypothesis

• >

• <

• =

A right-tailed (one-tailed) test uses this symbol in the alternative hypothesis

• $\ne$

• >

• <

• =

A two-tailed test uses this symbol in the alternative hypothesis

• $\ne$

• >

• <

• =

The significance level of a hypothesis test

• is the probability of a type I error

• is denoted by $\alpha$

• has an inverse relationship with $\beta$

• all of these
