What is the decision at a 0.05 level of significance for each of the following tests?...

  • What is the decision at a 0.05 level of significance for each of the following tests? Hint: Find the critical value for each test; then make a decision. (Round your critical values to two decimal places.)



  • Part (a)

    F(3, 28) = 2.98

    Fcrit =

    Retain the null hypothesis.Reject the null hypothesis.    

  • Part (b)

    F(5, 20) = 2.46

    Fcrit =

    Retain the null hypothesis.Reject the null hypothesis.    

  • Part (c)

    F(4, 34) = 2.72

    Fcrit =

    Retain the null hypothesis.Reject the null hypothesis.    

  • Part (d)

    F(2, 10) = 4.01

    Fcrit =

    Retain the null hypothesis.Reject the null hypothesis.
