In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6972 subjects randomly selected from an online group involved with ears. There were 1343 surveys returned. Use a 0.01 significance leve 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 O B.
