TABLE 11-8
An important factor in selecting database software is the time required for a user to learn how to use the system. To evaluate three potential brands (A, B and C) of database software, a company designed a test involving five different employees.

Below is the Excel output for the randomized block design:

-Referring to Table 11-8, what is the null hypothesis for testing the block effects?

• B) H₀: μ₁ = μ₂ = μ₃ = μ₄ = μ₅
• C) H₀: MA = MB = MC
• D) H₀: M₁ = M₂ = M₃ = M₄ = M₅
