The bottler of a certain soft drink claims its equipment to be accurate and that the variance of all filled bottles is .05 or less. The null hypothesis in a test to confirm the claim would be written as _____. A) H₀: σ² ≥ .05 B) H₀: σ² > .05 C) H₀: σ² < .05 D) H₀: σ² ≤ .05

Quizplus · Accepted Answer

The null hypothesis should state that the variance is equal to or greater than the claimed value, which is .05. Therefore, the correct choice is D as it states that the variance is less than or equal to .05.
