for some reason i can never find the volume of a sphere and i know how to but can someone help me please?

Aneli [31]

Answer:

113.1

Step-by-step explanation:

$V=\frac{4}{3} r^3\\V=\frac{4}{3} (3)^3\\113.1=\frac{4}{3} (3)^3\\V= 113.1$

This is the formula you have to follow, finding the volume of objects is hard without the formula and it's just something you'll have to memorize. BUt just remember to plug in the radius which is 3 in this problem, into the volume formula: $V=\frac{4}{3} r^3$

alisha [4.7K]

Answer:

Part a: So the number of business owners giving holiday gift to their employees from survey is 12.

Part b: p-value is 0.00003

Part c: value of p is less that a we reject the null hypothesis.

Step-by-step explanation:

Part a

number of business owners=20% x n

number of business owners= 0.2x 60

number of business owners=12

Part b

H0: p=0.46

H1: p<0.46

Here

n=60, $\hat{p}$ =0.2, p=0.46

So test statistics is given as

$z=\frac{\hat{p}-p}{\sqrt{\frac{p(1-p)}{n}}}\\z=\frac{0.20-0.46}{\sqrt{\frac{0.46(1-0.46)}{60}}}\\z=\frac{-0.26}{0.064}\\z=-4.04$

p-value is P(z<-4.04)= 0.00003

Part c

As value of p is less that a we reject the null hypothesis.
