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 .
Answer:
The slope is 5
Step-by-step explanation:
This equation is in slope intercept form
y = mx +b
where m is the slope and b is the y intercept
y = 5x+4
where 5 is the slope and 4 is the y intercept
The two correct answers are that even numbers represent Jim and odd numbers represent Rob, or odd numbers represent Jim and even numbers represent Rob.
Answer:
61.70% probability that he or she will be between 23 and 52 years of age
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d is given by the following formula.
The numbers of full-time wage and salary workers in each age category are almost uniformly distributed by age, with ages ranging from 18 to 65 years.
This means that 
. So
(a) what is the probability that he or she will be between 23 and 52 years of age?
61.70% probability that he or she will be between 23 and 52 years of age
