Answer:
0.3876<p<0.4389
Step-by-step explanation:
-Given
-We calculate the proportion of surveys returned:

For a 99% confidence interval:

#The margin of error is calculated as;

The confidence interval are then:
![CI=\hat p\pm ME\\\\=0.4134\pm 0.0255\\\\=[0.3876,0.4389]](https://tex.z-dn.net/?f=CI%3D%5Chat%20p%5Cpm%20ME%5C%5C%5C%5C%3D0.4134%5Cpm%200.0255%5C%5C%5C%5C%3D%5B0.3876%2C0.4389%5D)
Hence, the confidence interval is 0.3876<p<0.4389
