Think of something you’d like to build a confidence interval for, whether it be a population mean, proportion, or standard deviation. Find some reliable data online and compute a 95% confidence interval for that population parameter. Provide a reference your data and interpret your results.

Expert Solution

suppose we have two city ( city A and city B) and we want to study about difference in proportion of people in city A and city B who support to a candidate who is nominated for president election.

n1= sample size ( for city A).

X1 = number of people who support to condidate from city A.

P1= proportion of people who support to condidate from city A

n2 = sample size ( for city B)

X2=number of people who support to condidate from city B.

P2= proportion of people who support to condidate from city B.

People of city A and city B will be population 1 and population 2 respectively .

A person would like to create a 99% confidence interval for a particular unknown population proportion. They would like the interval to have a width no wider than 0.1 and do not yet have an estimate for the value of the unknown population proportion. How large of sample should they use in when creating this confidence interval?
