Mean: 67.7 (rounded to the nearest tenth)
Median: 52.2
Mode: 55
Step-by-step explanation:
To find the the mean is to take all the numbers, all them together and divide by how many numbers there is. 50+55+42+38+163+55+61= 564 then divided by 6 is 67.7
to find the median is to put all the numbers in order, (I prefer to go increasing order) and then find the middle number. If there is no middle number you take the two numbers around it and subtract them from one n another.
Mode is to find the most common number. Whichever number repeats itself

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
