Assume the population has a distribution with a mean of 110 and a standard deviation of 8. For a random sample of size 40, find

VARVARA [1.3K]

Answer:

109.33

Step-by-step explanation:

given that the population has a distribution with a mean of 110 and a standard deviation of 8

Sample size n = 40

Std error of sample mean = std dev/square root of sample size

= $\frac{8}{\sqrt{40} } \\=1.265$

From std normal distribution table we find that 30th percentile for Z is

-0.5244

Corresponding x score = $110-0.5244*1.265=109.33663$

30th percentile = 109.33663

=109.33

What is the value of x?

Kazeer [188]

Answer:

Step-by-step explanation:

The volume of a sphere is

$V=\frac{4}{3}\pi r^3$

We are told our volume is 500pi/3, so we fill that in and solve for r:

$\frac{500\pi}{3}=\frac{4}{3}\pi r^3$

Start by multiplying both sides by 3 over 4 pi:

$(\frac{3}{4\pi})\frac{500\pi}{3}=(\frac{3}{4\pi})\frac{4\pi}{3}r^3$

Simplifying gives us

$125=r^3$

Take the cubed root of both sides to get that

r = 5
