The contents of a sample of 26 cans of apple juice showed a standard deviation of .06 ounces. We are interested in testing whether the variance of the population is significantly more than .003. The null hypothesis is A) s² .003. B) s² ≤ .003. C) σ² .003. D) σ² ≤ .003.

Question

The contents of a sample of 26 cans of apple juice showed a standard deviation of .06 ounces. We are interested in testing whether the variance of the population is significantly more than .003. The null hypothesis is A) s² > .003. B) s² ≤ .003. C) σ² > .003. D) σ² ≤ .003.

Quizplus · Accepted Answer

The null hypothesis in this case is that the variance of the population is not significantly more than .003. This can be written as σ^2 ≤ .003. Therefore, the correct choice is D) σ² ≤ .003.
