• The failure to reject a false null hypothesis
• Rejecting a true null hypothesis
• The acceptance to reject a null hypothesis
• Accepting a true null  hypothesis

What is the only option for the null hypothesis? 

• H₀ = k
• H₀ > k
• H₀ < k
• H₀ ≠ k

Which of the following is not an option for an alternate hypothesis? 

• H_a = k
• H_a > k
• H_a < k
• H_a ≠ k

What is definition of null hypothesis?

• The independent variable has no effect on the dependent variable for the population
• The independent variable does have an effect on the dependent variable
• The dependent variable has no effect on the independent variable
• The dependent variable does have effec on the independent variable
