In a study of cell phone usage and brain hemispheric dominance,
an Internet survey was e-mailed to 6985 subjects randomly selected
from an online group involved with ears. There were 1295 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.
