In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6986 subjects randomly selected from an online group involved with ears. There were 1330 surveys returned. Use a 0.01 significance level to test the claim that the return rate is less than 20%. Use the P-value method and use the normal distribution as an approximation to the binomial distribution.
