A quality-assurance inspector periodically exam-ines the output of a machine to determine whether it is properly adjusted. When
Stolb23 [73]

Answer:

Step-by-step explanation:

From the given information;

The null hypothesis & alternative hypothesis:

\mathbf{H_o:\mu = 2}  \\ \\  \mathbf{H_1 : \mu \ne 2}

The test statistics can be computed as:

Z = \dfrac{\overline x - \mu}{\dfrac{\sigma}{\sqrt{n}}}

Z = \dfrac{2.025- 2}{\dfrac{0.07}{\sqrt{35}}}

Z = \dfrac{0.025}{\dfrac{0.07}{\sqrt{35}}}

Z =2.11

The p-value = 2(Z > 2.11)  since this is a two-tailed test

The p-value = 2( 1 - Z < 2.11)

The p-value = 2 (1 -0.9826)

The p-value = 2 (0.0174)

The p-value = 0.0348

Decision Rule: To reject the \mathbf{H_o}  if the p-value is less than \mathbf{H_o}

Conclusion: We fail to reject \mathbf{H_o} and conclude that the population mean = 2, thus the machine is properly adjusted.

Step-by-step explanation:

<em>The distributive property</em>:

<em>a(b + c) = ab + ac</em>

-\dfrac{1}{2}(4-6x)=\left(-\dfrac{1}{2}\right)(4)+\left(-\dfrac{1}{2}\right)(-6x)=-2+3x
