Question:

Refer to Section 6.4.1. When Y is N(µ_i, σ²), consider the comparison of (µ₁,....,µ₁) based on independent samples at the I categories of X. When approximately µ_i = α + βx_i, explain why the t or F test of H₀: β = 0 is more powerful than the one-way ANOVA F test. Describe a pattern for {µ_i} for which the ANOVA test would be more powerful.
