OneSample Z Cl Test of mu 5516 vs SolutionA As p 001 we FA

One-Sample Z: Cl Test of mu = 5.516 vs

Solution

A.

As p > 0.01, we FAIL TO REJECT THE NULL HYPOTHESIS.

[We reject the null if p < significance level.]

**************
B.

There is no sufficient evidence that the eman is greater than 5.516.

*****************

C.

From A, we fail to reject the null hypothesis as p > 0.01.

Thus, we have no evidence against the null to reject it, so we have no evidence to claim the alternative hypothesis.

**************

D.

As we failed to reject the null hypothesis, it could be a TYPE II (2) error.

Type 2 errors is failing to reject false null hypotheses.
