Step-by-step explanation:

We are given the following in the question:

Sample size, n = 1024

Sample proportion:

We have to find the margin of error associated with a 90% Confidence interval.

Formula for margin of error:

Putting the values, we get:

Thus, the margin of error for the survey is 0.016
