N a study of cell phone use and brain hemispheric dominance, an Internet survey was e-mailed to 2472 subjects randomly selected from an online group involved with ears. 1022 surveys were returned. Construct a 99% confidence interval for the proportion of returned surveys.

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:

Hence, the confidence interval is 0.3876<p<0.4389
