(Study Guide, Topic 1, Section 1.5)
1.2 Convert to formal statistical hypotheses (H₀ and H₁) using population symbols
H0:μ1=μ2(or μ1−μ2=0)H0:μ1=μ2(or μ1−μ2=0)H1:μ1>μ2(or μ1−μ2>0)H1:μ1>μ2(or μ1
−μ2>0)
μ1μ1 = population mean exam score for students who attend extra tutorials
μ2μ2 = population mean exam score for students who do not attend extra tutorials
