Consider the following information.
SSTR = 6750
H₀: μ₁ =μ₂ =μ₃ =μ₄= μ₅
SSE = 8000
H_a: At least one mean is different

The mean square due to treatments (MSTR) equals

Quizplus · Accepted Answer

We can calculate the MSTR using the formula MSTR = SSTR / dfT, where dfT is the degrees of freedom for treatments. From the information given, we know that there are five means being compared (μ₁, μ₂, μ₃, μ₄, and μ₅), so dfT = 5-1 = 4. Plugging in the values, we get MSTR = 6750 / 4 = 1687.5. Therefore, the correct answer is option C.
