The estimate is 
Step-by-step explanation:
From the question we are told that
The sample size is n = 522
The sample proportion of students would like to talk about school is 
Given that the confidence level is 90 % then the level of significance can be mathematically evaluated as
Next we obtain the critical value of 
from the normal distribution table, the value is
Generally the margin of error can be mathematically represented as
=> 
=> 
Generally the estimate the proportion of all teenagers who want more family discussions about school at 90% confidence level is
substituting values
When comparing two numbers, you usually start by comparing the numbers on the left of the decimal point, if you find one of them greater than the other, then you've got your answer ready. If the numbers on the left of the point are equal, then you start comparing the decimal part.
In the two numbers given, we have 87 and 13.688. We start by comparing the numbers before the point, we will find that these numbers are 87 and 13.
Comparing these two, we can see that 87 is greater than 13.
Therefore: 87 is greater than 13.688
The domain is going to be ur x values....the number of minutes
