To determine

To perform a 5% level of significance and write a conclusion.

Answer to Problem 41PT4

There is significant evidence that the mean electrical potential differs for normal mice and mice with diabetes.

Explanation of Solution

Given:

  

The null and alternative hypotheses:

  $\begin{array}{l}{H}_0:{\mu }_1={\mu }_2\\ H_a:{\mu }_1\ne {\mu }_2\end{array}$

Using excel,

  

Decision: P-value < 0.05, reject H₀.

Conclusion: There is significant evidence that the mean electrical potential differs for normal mice and mice with diabetes.
