Answer:

$80.75

Step-by-step explanation:

From the question, we are given the following parameters

Amount borrowed (principal)=$3800

Time=3 months =1/4 years

Rate = 8.5%

Required

Interest paid by the man

Using the simple interest formula;

SI= Principal*Rate*Time/100

SI=3800*8.5*0.25/100

SI=38*8.5*0.25

SI=$80.75

Hence the man paid $80.75 for the use of the money

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.
