, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
For this problem, we have that:
92% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).

A 15 - pack would cost $6.90.
Explanation:
We know that a 6-pack of fruit juice would cost 2.76, so to find the cost of 1 -pack, you divide 2.76 by 6. That gives us $0.46 for 1 -pack. To find the cost of a 15-pack, you would multiply $0.46 by 15, which gives us $6.90. Therefore, a 15- pack would cost $6.90

Answer:
<h3>15%</h3>
Step-by-step explanation:
<h3>First , We will solve their daily Income </h3>
• Income = spends / rate
• Income = 600 / 40%
• Income = 600 / 0 .40%
• Income = 1500
Thus , Their daily Income is 1500 . Now ,We will solve for the rate of the Allowance .
• Rate = spent / Income
• Rate = 225 / 1500
• Rate = 0.15
• Rate = 15%
Therefore, the percent of the family's daily Income of the Allowance of their children's is 15%
