Question

In a study of cell phone usage and brain hemispheric dominance, an Internet survey was e-mailed to 6982 subjects randomly selected from an online group involved with ears. There were 1315 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.

Answer #1

In a study of cell phone usage and brain hemispheric dominance,
an Internet survey was e-mailed to 6969 subjects randomly selected
from an online group involved with ears. There were 1326 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.

In a study of cell phone usage and brain hemispheric dominance,

from an online group involved with ears. There were 1328 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.

In a study of cell phone usage and brain hemispheric dominance,
an Internet survey was e-mailed to 6999 subjects randomly selected
from an online group involved with ears. There were 1316 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.
What is The test statistic?

In a study of cell phone usage and brain hemispheric dominance,
an Internet survey was e-mailed to 6990 subjects randomly selected
from an online group involved with ears. There were 1348 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.
Identify the P Value

In a study of cell phone usage and brain hemispheric dominance,
an Internet survey was e-mailed to 6987 subjects randomly selected
from an online group involved with ears. There were 1500 surveys
returned. Use a 0.01 significance level to test the claim that the
return rate is greater than 20%. Use the P-Value method and use the
normal distribution as an approximation to the binomial
distribution. (Hint: may use the appropriate calculator
function).

In a study of cell phone usage and brain hemispheric dominance,
an Internet survey was e-mailed to 6955 subjects randomly selected
from an online group involved with ears. There were 1307 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.
