Answer:
a) 95% confidence interval for the population proportion of all young adults in Kentucky who received help from their parents.
( 0.0761 , 0.3239)
b) Margin of error = 0.1264.
Step-by-step explanation:
<u>Explanation</u>:-
Given '8' persons in a random sample of 40 young adults who recently purchased a home in Kentucky received help from their parents.
sample proportion of success
q = 1=p
q = 1-0.2 = 0.8
a)
95% confidence interval for the population proportion of all young adults in Kentucky who received help from their parents.
(0.2 - 0.1239,0.2+0.1239)
( 0.0761 , 0.3239)
b) the margin of error for a 95% confidence interval for the population proportion.
For the 95% confidence interval ∝= 0.05 and zₐ = 1.96≅2.
Margin of error for a 95% confidence interval for the population proportion.
Margin of error = 0.1264.
