Suppose that four normal populations with common variance

Chapter 13, Problem 32E

(choose chapter or problem)

Suppose that four normal populations with common variance \(\sigma^{2}\) are to be compared with a sample size of eight observations from each population. Determine the smallest value for \(\Sigma_{i=1}^{4} \tau_{i}^{2} / \sigma^{2}\) that can be detected with power \(90 \%\). Use

\(\alpha=0.05\).
