In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6984 subjects randomly selected from an online group involved with ears. There were 1318 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. Identify the null hypothesis and alternative hypothesis. O A. Ho: p = 0.2 Hy:p<0.2 O B. Ho:p>0.2 Hi: p = 0.2 D. Ho:p70.2 Hy: P = 0.2 C. Ho:p < 0.2 Hy: p = 0.2 E. Ho: P = 0.2 Hy:p80.2 O 0 F. Ho: p = 0.2 Hy:p>0.2
