There were 1287 surveys returned. Use a 0.01 significance level to test the claim that the return is less than 20 % ........

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. Th 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 = 02 Hy: p # 0.2 Hyp 02 H1 : p = 02 H1 p = 02 O E. Ho P = 0.2 OF. Ho P 02 H1 p = 02 The test statistic is z= (Round to two decimal places as needed. ) The P-value is (Round to three decimal places as needed.) Because the P-value is the significance level, the null hypothesis. There is evidence to support the claim that the return rate is less than 20
