Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
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 z-score that has a p-value of 
.
The margin of error is of:
In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that 
95% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
Margin of error:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.

Answer:
30 years
Step-by-step explanation:
Forming Algebraic expressions and solving them to find the age.
Ratio of age of mother and daughter = 5 : 3
Age of mother = 5x
Age of daughter = 3x
It is given that mother's age is 50 years.
⇒ 5x = 50
Divide both sides by 5.
x = 50÷5
x = 10
Daughter's age = 3x
= 3*10
= 30 years
