Volgvan

Answer:

Volume (V) = 2522.0 mm^3

Step-by-step explanation:

The volume of cylinder is :

V = π r 2 h

We know that the height (h) is 19.

We also know the radius (r) is 13/2 = 6.5

So,

V = π 6.5^2*19

V = 2522.0 mm^3

Last year, 46% of business owners gave a holiday gift to their employees. A survey of business owners indicated that 20% plan to

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.
