Transcribed Image Text:In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6970 subjects randomly selected from an online group involved with ears. There were 1315 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.
OA. Ho: P<0.2
H₁: p=0.2
OC. Ho: p=0.2
H₁: p>0.2
OE. Ho: p0.2
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
OL
the significance level,
the null hypothesis. There is
reject
fail to reject

OB. Ho:p>0.2
H₁: p=0.2
OD. Ho: p=0.2
H₁ p<0.2
OF. Ho: p=0.2
H₁: p=0.2
F11
evidence to support the claim that the return rate is less than 20%
