Answer:
The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, 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).

Answer:
W(x) = 0.06x +30
Step-by-step explanation:
The withholding on the student's salary is ...
W(S(x)) = 0.10(0.60x +300) = 0.06x +30
Where x is the number of ice cream bars sold, the withholding is ...
W(x) = 0.06x +30
<h3>
Answer: 30</h3>
Reason:
I'm assuming that the swimmer travels along the 50 meter side
Divide 1500 over 50 to get 1500/50 = 30, which tells us that the swimmer must make 30 trips.
