Molodets [167]

Answer: $60,540< \mu$

Step-by-step explanation:

The confidence interval for population mean is given by :-

$\overline{x}-z^*\dfrac{\sigma}{\sqrt{n}}< \mu$

, where $\sigma$ = Population standard deviation.

n= sample size

$\overline{x}$ = Sample mean

z* = Critical z-value .

Given : $\sigma=\$17,000$

n= 49

$\overline{x}= \$65,300$

Two-tailed critical value for 95% confidence interval = $z^*=1.960$

Then, the 95% confidence interval would be :-

$65,300-(1.96)\dfrac{17000}{\sqrt{49}}< \mu$

$=65,300-(1.96)\dfrac{17000}{7}< \mu$

$=65,300-4760< \mu$

$=60,540< \mu$

Hence, the 95% confidence interval for estimating the population mean $(\mu)$ :

$60,540< \mu$

A hemisphere has a diameter of 26 centimeters. What is the volume of a sphere with the same radius?

salantis [7]

$r= \frac{d}{2}= \frac{26}{2} \;\Rightarrow r=13\,cm \\ \\ 
V= \frac{4}{3} \pi r^3 \\ \\ 
V= \frac{4}{3} \pi \,(13)^3 \\ \\ 
V= \dfrac{4\cdot 2197}{3} \pi \\ \\ 
V= \frac{8788}{3} \pi\approx 9202,77\,cm^3$
