State the decision and conclusion (in a complete sentence) for the following preconceived levels of \(\alpha\).

\(\alpha=0.01\)

a. Decision:____

b. Reason for the decision:____

c. Conclusion:(write out in complete sentence):___

Short Answer

Expert verified

Part a. Decision: here \(\alpha=0.01\) so “reject the null hypothesis”.

Part b. Reason for the decision: \(p-value<\alpha\) so \(p-\)value is \(0\).

Part c. Conclusion (write out in a complete sentence): reject the null hypothesis so the alternative got accepted so there is sufficient evidence to conclude that smoking level is dependent on the ethnic group.
