The bottler of a certain soft drink claims their equipment to be accurate and that the variance of all filled bottles is at most .05.The null hypothesis in a test to confirm the claim would be written as

A) H₀: σ² ≥ .05.
B) H₀: s² ≥ .05.
C) H₀: s² ≤ .05.
D) H₀: σ² ≤ .05.

Question

Zybrea Knight · Accepted Answer

Final Answer : D, Explanation :  The null hypothesis should include the population variance and state that it is less than or equal to the given value of .05. Choice D correctly does this by stating that the population variance (σ) is less than or equal to .05.
