**ANSWER:---------**

From the Information.

Top Sample size of Adult residents (n)= 200 out of which to has kides that is (X) - 110 The sample of proportion of those who have kide that is parents can be obtained an- x P = n. 110 0.55 200 point estimate Ch): 0.55. since the value of 2/2 at 90%. Confidence interval is = 1645 Cusing NORM.S. INV C1-0:10) CS Scanned with Camscanne

Now, The Margin of Error can be calculated as- Margin of Error, E=22/2 (1-6 n.

E = 1.645x10.55(1-0.55) 200: - 1.645 0.55(0.45) 200 =loles 0.2475 200 1.645J 0.0012375 1. 645 (0.035) E = 0.0575 30-058 CS Scanned with Camcamat

Now, the 901. confidence interval for population proportion can be calculated as. ст dla PitE -[0.55 +0.058] oll = [0.55-0.058, 0.55 +0.058] = [0.492, 0.608 ... The ci for population proportion ê is 0-492]< $25.608 CS Scarved with Camacanner
