Question

A soft drink filling machine,when in perfect adjustment,fills the bottles with 12 ounces of soft drink.Any over filling or under filling 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: $\mu$ $\le$12 B)H₀: $\mu$ $\le$ 12 H_a: $\mu$ > 12 C)H₀: $\mu$ $\neq$12 H_a: $\mu$ = 12 D)H₀: $\mu$ = 12 H_a: $\mu$ $\neq$ 12

Quizplus · Accepted Answer

The null hypothesis (H0) should state that the machine is properly adjusted, meaning the mean fill is 12 ounces. The alternative hypothesis (Ha) should indicate any deviation from this, whether over or under filling, which is represented by $\mu \neq 12$.
