$5a-(8-a)=4a-10 \\
5a-8+a=4a-10 \\
6a-8=4a-10 \\
6a-4a=-10+8 \\
2a=-2 \\
a=-1$

<u /> $5a-(8-a)=4a-10\ \ \ |Omit\ the\ bracket\\\\
5a-8+a=4a-10\\\\
6a-8=4a-10\ \ \ |Subtract\ 4a\\\\
2a-8=-10\ \ \ |Add\ 8\\\\

A large box contains 10,000 ball bearings. A random sample of 120 is chosen. The sample mean diameter is 10 mm, and the standard

ser-zykov [4K]

Answer:

Option a) A 95% confidence interval for the mean diameter of the 120 bearings in the sample is $10 \pm 1.96\displaystyle\frac{0.24}{\sqrt{120}}$ .

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 120

Sample mean = 10 mm

Standard Deviation = 0.24 mm

Formula:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

$10 \pm 1.96\displaystyle\frac{0.24}{\sqrt{120}}$

Hence, the correct interpretation for the confidence interval is given by option a).

A 95% confidence interval for the mean diameter of the 120 bearings in the sample is $10 \pm 1.96\displaystyle\frac{0.24}{\sqrt{120}}$ .

We have to consider the factor of sampling of 120 ball bearings from a population of 10,000 ball bearings.
