In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6996 subjects randomly selected from an online group involved with ears. There were 1303 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
О В. Но р<0.2
H, p=0.2
O C. Ho p=0.2
H, p 0.2
O D. Ho p 0.2
H, p= 02
OF. Ho p=0.2
H, p>02
O E. Ho p=0.2
H: p<0.2
The test statistic is z =
ur
(Round to two decimal places as needed.)
The P-value is
(Round to three decimal places as needed.)
Because the P-value is
V the significance level,
V the null hypothesis. There is
V evidence to support the claim that the return rate is less than 20%.
