In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6967 subjects randomly selected from an online group involved with ears. There were 1342 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>02 O B. Ho p<02 H, p=0.2 H, p=0.2 O C. Ho p 02 H p=02 O E. Ho p=0.2 H p>02 D. Ho p=02 H, p<02 OF.
