Answer: 10 customers.
Step-by-step explanation:
The formula to find the required sample size :
(1)
, where p= prior population proportion.
n= sample size.
= Population standard deviation from previous studies.
Let p be prior population proportion of the customers who click on ads on their smartphones .
As per given , we have
p=0.62
E= 0.27
For 92% confidence , significance level : 
The critical value of z for 92% confidence interval from z-table would be

Put theses values in the formula (1), we will get


Therefore , the company should survey 10 customers .
If I'm really it correctly, V = 5^3
v = s^3
s = 5
V = 5*5*5
V = 25*5 That's 2 fives multiplied together.
V = 125 cubic units.

Answer:
- 267/200 = 1.335
- 131/150 = 0.8733...
- 1/10,000 = 0.0001
- 1/12 = 0.0833...
Step-by-step explanation:
It might be helpful to think of the % symbol as being interchangeable with /100.
133 1/2% = (133 1/2)/100 = 267/200 = 1.335
87 1/3% = (87 1/3)/100 = 262/300 = 131/150 = 0.8733333... (repeating 3)
0.01% = 0.01/100 = 1/10000 = 0.0001
8 1/3% = (8 1/3)/100 = 25/300 = 1/12 = 0.0833333... (repeating 3)
