A random sample of five Galaxy 8 smartphones is selected from the production line after final assembly, and the result of the we

zepelin [54]

<h2>Answer with explanation:</h2>

Given : A random sample of five Galaxy 8 smartphones is selected from the production line after final assembly, and the result of the weight control measurement is (in grams) are :

X= 155.1, 154.8, 155.5, 155.3, and 154.6.

here, n=5

The average weight : $\overline{x}=\dfrac{\sum^{i=5}_{i=1}x_i}{n}$

$=\dfrac{155.1+154.8+155.5+155.3+154.6}{5}\\\\=\dfrac{775.3}{5}=155.06$

∴ Average weight ( $\overline{x}$ )=155.06 grams

Uncertainty = Standard deviation: $\sigma=\sqrt{\dfrac{\sum^{i=5}_{i=1}(x_i-\overline{x})^2}{n}}$

$=\sqrt{\dfrac{(0.04)^2+(-0.26)^2+(0.44)^2+(0.24)^2+(-0.46)^2}{5}}$

$=\sqrt{\dfrac{0.532}{5}}=\sqrt{0.1064}=0.326190128606\approx0.33$

i.e. Its uncertainty : $\sigma=0.33$

The fractional uncertainty = $\dfrac{\sigma}{\overline{x}}$

$=\dfrac{0.33}{155.06}=0.00212820843544\approx0.002$
