Statıstıcs Iı Deneme Sınavı Sorusu #1062004

For Group 1 and Group 2 data that are normally distributed, and the population variances are not equal, we can we conclude that there is a the mean of Group 1 is greater than the mean of Group 2. What is the alternative hypothesis?

H₁: µ₁≠ µ₂

H₀ : µ₁ ≠ µ₂

H₁ : µ₁< µ₂

H₀: µ₁> µ₂

H₁: µ₁> µ₂

Yanıt Açıklaması:

Since the claim in the question is the first group’s mean is greater than the second group, the alternative hypothesis is right-tailed (right sided). Then the hypothesis can be expressed as follows:

H₀ : µ₁ = µ₂ or H₀: µ₁ – µ₂ = 0
H₁: µ₁> µ₂ or H₁: µ₁ – µ₂ > 0

The answer is E.
