Chapter 21, Problem 6E

To determine

To explain would you have made the same decision at $\alpha =0.10$ and how about $\alpha =0.01$ .

Answer to Problem 6E

No, we do not have same decision at $\alpha =0.10$ but at $\alpha =0.01$ , we have made.

Explanation of Solution

It is given in the question that environmental concerned about the impact of high frequency radio transmissions on birds found that there was no evidence of a higher mortality rate among hatchlings in nests near cell towers. Thus, no, we would not have made the same decision at $\alpha =0.10$ because we only know that P-value is greater than $0.05$ but we have no idea whether it is also greater than $0.10$ . And we have made the same decision at $\alpha =0.01$ because the p-value is greater than $0.05$ , it also has to be greater than $0.01$ , so we would again reject the null hypothesis.
