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, =0.2, p=0.46
So test statistics is given as
p-value is P(z<-4.04)= 0.00003
Part c
As value of p is less that a we reject the null hypothesis.
