Revisiting Exercise 05

Key ideas

• Two samples, A, B
• We determine sample size (\(n_A\), \(n_B\)), effect size (\(d\)), mean (\(mu_A\), \(mu_B=mu_A+d\)), standard deviation (\(\sigma_A\), \(\sigma_B\)), and the criterion value for our \(t\) test, (\(\alpha\)).
• Research question: Is A == B?
• If \(d \neq 0\), then there is an effect: \(A \neq B\)
  • But can our \(t\) test detect it?
