Question

Determine the margin of error for a confidence interval to estimate the population proportion for the following confidence levels with a sample proportion equal to 0.35 and n= 120

the margin of error for a confidence interval to estimate the population portion for 90% confidence level is

the margin of error for a confidence interval to estimate the population portion for 95% confidence level is

the margin of error for a confidence interval to estimate the population portion for 97% confidence level is

Answer #1

p = 0.35, n =120

1. Confidence interval =90%

At
= 1-0.90 =0.10, critical value,
z_{c}=ABS(NORM.S,INV(0.10/2) )= 1.645

Margin of error, E =

-------------------------------------------

2. Confidence interval =95%

At
= 1-0.95 =0.15, critical value,
z_{c}=ABS(NORM.S,INV(0.05/2) )= 1.96

Margin of error, E =

-------------------------------------------

3. Confidence interval =97%

At
= 1-0.97 =0.03, critical value,
z_{c}=ABS(NORM.S,INV(0.03/2) )= 2.170

Margin of error, E =
