Answer:
We are 95% confident that the true proportion of adults overweight is between 0.644 and 0.672
Step-by-step explanation:
We can begin founding the estimated proportion of people overweight:

We need to find a critical value for the confidence level using the normal standard distribution. We know that 95% is the confidence level, then the significance level would be given by
and
. And the critical value would be given by:
The confidence interval for the true population proportion of interest is given by the following formula:
Replacing the data provided we got:
We are 95% confident that the true proportion of adults overweight is between 0.644 and 0.672
