For the specified margin of​ error, confidence​ level, and educated guess for the observed​ value, obtain a sample size that will ensure a margin of error of at most the one specified​(provided, of​ course, that that observed value of the sample proportion is further from 0.5 than the educated​ guess). Margin of errorequals= 0.04​
Confidence levelequals=95%
Educated guessequals=0.32

n=?

The appropriate answer is "523".

Step-by-step explanation:

Given:

Margin of error,

E = 0.04

Confidence level,

= 95%

Educated guess,

= 0.32

According to the question,

The sample size will be:

⇒

By substituting the values, we get

or,

283 square feet

step-by-step explanation:

good luck
