In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6955 subjects randomly selected from an online group involved with ears. There were 1310 surveys retumed. 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 H p=0.2 O B. Ho p=0.2 H,: p>0.2 YO D. Ho p=0.2 H, p<0.2 OC. Ho p<0.2 H p=02 O E. Ho p=0.2 H, p#0.2 OF. Ho p#0.2 H 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.) hat the return rate is less than 20%

In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6955 subjects randomly selected from an online group involved with ears. There were 1310 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 H p=0.2 O B.

The P-value is (Round to three decimal places as needed.) the null hypothesis. There is V evidence to support the claim that the return rate is less than 20%. Because the P-value is V the significance level,
