Answer:

shows a cone pouring water twice into a sphere with the same radius/height to fill it to the top. Because it takes two cones to fill one sphere, we can use the volume of a cone formula as a starting point to derive the volume of a sphere

<u>Confidence Interval</u>

When the population standard deviation $\sigma$ is known, the formula for a confidence interval for a population mean $\bar x$ is:

$\displaystyle \bar x \pm z\frac{\sigma}{\sqrt{n}}$

Where n is the sample size and z is the corresponding z-value from the standard normal distribution for the selected confidence level. The value of z for a 95% confidence interval is z=1.96. The rest of the values are

$\bar x=28.2,\ \sigma=2.7, \ n=10$
