The margin of error for the provided confidence interval is 0.015.

The margin of error for a confidence interval for a population proportion can be calculated using the following formula:

Margin of Error = EBP - p^

Given the confidence interval (0.33,0.36) and the sample proportion p^ = 0.345, we can calculate:

Margin of Error -

= 0.36 - 0.345

= 0.015

Therefore, the margin of error is 0.015.
