In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6993 subjects randomly selected from an online group involved with ears. There were 1293 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 OB. Ho: P = 0.2 H1 : p # 0.2 H 1 : p > 02 C. Ho: P=0.2 O D. Ho: p 0.2 H1 : p= 0.2 H1 : p = 0.2 The test statistic is z =. (Round to two decimal places as needed.)
