Question
In a study of cell phone usage and brain hemispheric dominance, an Intemet survey was e-mailed to 6992 subjects randomly selected from an online group involved with ears. There were 1294 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
Hy:p 0.2
O B. Ho: p>0.2
H1 p 0.2
O c. Ho p# 0.2
D. Ho: p 0.2
H p 0.2
H1 p 0.2
OE. Ho p 0.2
O F. Ho p 0.2
H1 p>0.2
Hy: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.)
the significance level,
Because the P-value is
the null hypothesis. There is
evidence to support the claim that the return rate is less than 20%
