Identify the null hypothesis and alternative hypothesis. OA. Ho: p=0.2 H₁: p<0.2 OC. Ho: p=0.2 H₁: p*0.2 O E. Ho: p<0.2 H₁: p=0.2 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, OB. Ho: p>0.2 H₁: p=0.2 O D. Ho: p=0.2 H₁: p>0.2 OF. Ho: p*0.2 H₁: p=0.2 the null hypothesis. There is evidence to support the claim that the return rate is less than 20

Question
In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6982 subjects randomly selected from an online group involved with ears. There were 1309 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 H₁: p<0.2 O C. Ho: p=0.2 H₁: p=0.2 O E. Ho: p<0.2 H₁: p=0.2 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, 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 the null hypothesis. There is evidence to support the claim that the return rate is less than 20%.
