In a study of cell phone usage and brain hemispheric dominance, an Intemet survey was e-mailed to 6971 subjects randomly selected from an online group involved with ears. There were 1347 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=02 O B. Ho p 0.2 H p=02 H, p<02 OC. Ho p<02 H,: p=0.2 OD. Ho p=0.2 H p>02 O E. Ho p=02 OF. Ho p>0.2 H, p#02 H, p=0.2 The test statistic is z = (Round to two decimal places as needed.)

In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6,971 subjects randomly selected from an online group involved with ears. There were 1,347 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.** \( H_0: p = 0.2 \) \( H_1: p < 0.2 \) - **B.** \( H_0: p \neq 0.2 \) \( H_1: p = 0.2 \) - **C.** \( H_0: p < 0.2 \) \( H_1: p = 0.2 \) - **D.** \( H_0: p = 0.2 \) \( H_1: p > 0.2 \) - **E.** \( H_0: p = 0.2 \) \( H_1: p \neq 0.2 \) - **F.** \( H_0: p > 0.2 \) \( H_1: p = 0.2 \) **The test statistic is \( z = \underline{\hspace{1cm}} \)** (Round to two decimal places as needed.)
