When an opinion poll uses random digit dialing to select respondents for polls, the response rate is approximately 10%10% for people contacted by cell phone. You watch a pollster dial 2020 cell numbers many times using random digitdialing.

(c) Suppose that the probability of getting a response were =0.05.p=0.05. How does this new p affect the standarddeviation?

When =0.05,p=0.05, =1.=1.

When =0.05,p=0.05, =0.2236.=0.2236.

When =0.05,p=0.05, =0.9747.=0.9747.

When =0.05,p=0.05, =4.3589.=4.3589.

What would be the standard deviation if =0.01?p=0.01? Give your answer to three decimalplaces.
