In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6997 subjects randomly selected from an online group involved with ears. There were 1305 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
OC. Ho: p<0.2
H, p=0.2
H p#02
O D. Ho p>0.2
H p=02
O E. H p=0.2
H p>02
E Ha: p=0.2
H p<02
The test statistic is z=
