    Which of the following descriptions of null hypothesis are correct? (Select all that apply)
    a. A null hypothesis is a hypothesis tested in significance testing.
    b. The parameter of a null hypothesis is commonly 0.
    c. The aim of all research is to prove the null hypothesis is true

    b. is false because a parameter can be anything we choose it to be

    d. is false since a p-value below 0.05 is often the rejection level.
