Question
In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6959 subjects randomly selected from an online group involved with ears. There were 1319 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 B. Ho p= 0.2
O A. Ho p<0.2
H:p=0.2
H1:p<0.2
O D. Ho p 0.2
O C. Ho: p=0.2
H:p>0.2
H:p=0.2
O E. Ho p>0.2
H1ip=0.2
O F. Ho p=0.2
H: p#0.2
The test statistic is z =
