Question

A soft drink filling machine, when in perfect adjustment, fills the bottles with 12 ounces of soft drink. 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 _____.

Answer 1

Answer:

$\mathbf{H_o : \mu = 12} \\ \\ \\ \mathbf{H_a: \mu \ne 12}$

Step-by-step explanation:

Given that:

The population mean μ =  12

By computing the null and alternative hypotheses, the correct set of hypotheses for this test is:

$\mathbf{H_o : \mu = 12} \\ \\ \\ \mathbf{H_a: \mu \ne 12}$

This is a two-tailed test.
