In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6964 subjects randomly selected from an online group involved with ears. There were 1302 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. A. Ho: p=0.2 H₁: p>0.2 O C. Ho: p0.2 H₁: p=0.2 E. Ho: p=0.2 H₁: p<0.2 -0. (Round to two decimal places as needed.) The test statistic is z = B. Ho: p<0.2 H₁: p=0.2 D. Ho:p>0.2 H₁: p=0.2 OF. Ho: p=0.2 H₁: p=0.2
