A public interest group hires students to solicit donations by telephone. After a brief training perod students make cals to potential donors and are paid on a commission basis. Experience indicates that early on, these students tend to have only modest success and that 70% of them give up their jobs in their first two weeks of employment. The group hires 5 students, which can be viewed as a random sample. Answer parts a. and b. below. a. What is the probability that at least 2 of the 5 will give up in the first two weeks? (Round to four decimal places as needed.)

Organ Donors USA Today provided information about a survey of 5100 adult Internet users. Of the respondents, 2346 said they are willing to donate organs after death. In this survey conducted for Donate Life America, 100 adults were surveyed in each state and the District of Columbia, and results were weighted to account for the different state population sizes. a. What percentage of respondents said that they are willing to donate organs after death? b. Based on the poll results, what is the probability of randomly selecting an adult who is willing to donate organs after death? c.

An observational study is described. Identify the specified element.At St. Luke's hospital in 1998, 674 women were diagnosed with breast cancer. Five years later, 88% of the Caucasian women and 83% of the African American women were still alive. Determine the nature and scope of the conclusion the study can reach. Choose the best answer below: A. Since there is no random assignment, there is no way to know that being Caucasian causes women with breast cancer an increased chance of surviving five years; there may have been confounding variables. B. For women with breast cancer, being Caucasian causes an increased chance of surviving five years. C. Since there is no random assignment, there is no way to know that being Caucasian causes women with breast cancer an increased chance of surviving five years; there may have been lurking variables. D. For Caucasian and African American women with breast cancer, attending St. Luke's hospital causes an increased chance of surviving five…

Use the data in the following table that shows results from a polygraph (lie detector) conducted by researchers Charles R. Honts and Gordon H. Barland. In each case, it was known if the subjects lied or did not lie, so the table indicates when the polygraph was correct. If two different subjects are randomly selected without replacement, find the probability that they both lied.
