Emma wants to estimate the percentage of people who use public transportation in a city. she surveys 400 individuals and finds that 104 use public transportation. find the margin of error for the confidence interval for the population proportion with a 90% confidence level.

0.036

Step-by-step explanation:

The formula of Margin of Error :-

Given : Sample size : n= 400

The proportion of individuals use public transportation.=

Level of confidence = 0.90

Significance level :

Critical value :

Then, we have

Hence, the margin of error for the confidence interval for the population proportion with a 90% confidence level. = 0.036
