Chapter 8: Q.68 (page 481)

List two difficulties the company might have in obtaining random results, if this survey were done by email.

Short Answer

Expert verified

When a survey is conducted via email, the sample is likely to be skewed due to the fact that the email addresses of some members of the population will be unknown, making it difficult to acquire a genuinely random sample from the population.

Step by step solution

01

Given Information

A portion of the population will be excluded due to selection or undercover age bias.

Measurement or response bias is a technique that produces results that differ from the genuine value.

Nonresponse bias occurs when there isn't enough data for everyone in the sample.

02

Explanation

If the survey is conducted via email, the sample is likely to be skewed due to non-response bias, as many respondents will not respond to the email. Furthermore, the persons with the strongest opinions are more likely to respond to the email voluntarily, skewing the sample results. As a result, the first challenge will be obtaining data for each individual to whom the mail is delivered.

Suppose that a committee is studying whether or not there is waste of time in our judicial system. It is interested in

the mean amount of time individuals waste at the courthouse waiting to be called for jury duty. The committee randomly

An article regarding interracial dating and marriage recently appeared in the Washington Post. Of the 1,709randomly selected adults, 315identified themselves as Latinos, 323identified themselves as blacks, 254identified themselves as Asians, and 779identified themselves as whites. In this survey, 86%of blacks said that they would welcome a white person into their families. Among Asians, 77%would welcome a white person into their families, 71%would welcome a Latino, and 66%would welcome a black person.

a. We are interested in finding the 95%confidence interval for the percent of all black adults who would welcome a white person into their families. Define the random variables Xand P', in words.

b. Which distribution should you use for this problem? Explain your choice.

c. Construct a 95%confidence interval.
