A juice drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of drink on an average.Any overfilling or underfilling results in the shutdown and readjustment of the machine.To determine whether or not the machine is properly adjusted, the correct set of hypotheses is A) H₀: $\mu$ 12. C) H₀: $\mu$ $\neq$ 12 H_a: $\mu$ = 12. D) H₀: $\mu$ = 12 H_a: $\mu$ $\neq$ 12.

Question

A juice drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of drink on an average.Any overfilling or underfilling results in the shutdown and readjustment of the machine.To determine whether or not the machine is properly adjusted, the correct set of hypotheses is A) H₀: $\mu$ < 12 H_a: $\mu$$\ge$ 12. B) H₀: $\mu$$\leq$ 12 H_a: $\mu$ > 12. C) H₀: $\mu$ $\neq$ 12 H_a: $\mu$ = 12. D) H₀: $\mu$ = 12 H_a: $\mu$ $\neq$ 12.

The null hypothesis (H0) should state that the machine is properly adjusted, which means the mean fill is 12 ounces. The alternative hypothesis (Ha) should state that the machine is not properly adjusted, meaning the mean fill is not 12 ounces.
