Question

For each of the following situations, suppose LaTeX: H_0: mu_1 = mu_2 H 0 : ? 1 = ? 2 is being tested against LaTeX: H_1: mu_1 eq mu_2 H 1 : ? 1 ? ? 2 . State whether or not there is significant evidence for the alternative hypothesis.

p-value = 0.046, alpha = 0.02

      [ Choose ]            Sufficient evidence for the alternative hypothesis.            Insufficient evidence for the alternative hypothesis.      

p-value = 0.033, alpha = 0.05

      [ Choose ]            Sufficient evidence for the alternative hypothesis.            Insufficient evidence for the alternative hypothesis.      

to = 2.26 with 5 df, alpha = 0.10

      [ Choose ]            Sufficient evidence for the alternative hypothesis.            Insufficient evidence for the alternative hypothesis.      

to = 1.94 with 16 df, alpha = 0.05

[ Choose ]            Sufficient evidence for the alternative hypothesis.            Insufficient evidence for the alternative hypothesis.   

Explanation / Answer

Since p-value = 0.046 is greater than alpha = 0.02, so fail to reject the null hypothesis.

  Insufficient evidence for the alternative hypothesis.

--------------------------

Since p-value = 0.033 is not greater than alpha = 0.05, so reject the null hypothesis.

Sufficient evidence for the alternative hypothesis.  

---------------------

The p-value for to = 2.26 with 5 df is 0.073.

Since p-value = 0.073 is not greater than alpha = 0.10, so reject the null hypothesis.

Sufficient evidence for the alternative hypothesis.  

-------------------

The p-value for to = 2.26 with 5 df is 0.070.

Since p-value = 0.070 is greater than alpha = 0.05, so fail to reject the null hypothesis.

  Insufficient evidence for the alternative hypothesis.
