In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6961 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 less than 20%. Use the P-value method and use the normal distribution as an approximation to the binomial distribution.

Question
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,
the null hypothesis. There is
OB. He: p=0.2
H₁: p*0.2
O D. He: p= 0.2
H₁: p>0.2
OF. He: p=0.2
H₁: p<0.2
evidence to support the claim that the return rate is less than 20%.
