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.

damaskus [11]

Answer:

<h2>$46.2</h2>

Step-by-step explanation:

p\%=\dfrac{p}{100}\\\\10\%=\dfrac{10}{100}=\dfrac{1}{10}=0.1\\\\10\%\ of\ \$42\to0.1\cdot\$42=\$4.2\\\\\$42+\$4.2=\$46.20

Other method:

\text{Increase bo}\ 10\%\to100\%+10\%=110\%\\\\110\%=\dfrac{110}{100}=\dfrac{11}{10}=1\dfrac{1}{10}=1.1\\\\110\%\ of\ \$42\to1.1\cdot\$42=\$46.2
