Answer:

$\boxed{V = 434.9 \ cm^3 }$

Step-by-step explanation:

Volume of Sphere = $\frac{4}{3} \pi r^3$

Where r = 4.7 cm

V = $\frac{4}{3} (3.14)(4.7)^3$

V = $\frac{4}{3} (3.14)(103.8)$

V = $\frac{1304.7}{3}$

V = 434.9 cm³ (Up to 1 dp)

Answer:

17,750
1737

Step-by-step explanation:

A suitable table or calculator is needed.

One standard deviation from the mean includes 68.27% of the total, so the number of bottles in the range 20 ± 0.16 ounces will be ...

0.6827·26,000 = 17,750 . . . . . within 20 ± 0.16

The number below 1.5 standard deviations below the mean is about 6.68%, so for the given sample size is expected to be ...

0.66799·26,000 = 1737 . . . . . below 19.76

<em>Comment on the first number</em>

The "empirical rule" tells you that 68% of the population is within 1 standard deviation (0.16 ounces) of the mean. When the number involved is expected to be expressed to 5 significant digits, your probability value needs better accuracy than that. To 6 digits, the value is 0.682689, which gives the same "rounded to the nearest integer" value as the one shown above.
