Recall the estimate by the Pew Research Center that 62% of U.S. adults favor the death penalty for murder. The same report gave a much lower estimate for the percentage of U.S. college graduates supporting the death penalty in cases of murder. According to census data from 2000, roughly 28% of U.S. adults have a college degree.What is the probability that a randomly selected U.S. adult has a college degree and favors the death penalty?Let A be the event that a U.S. adult has a college degree. Let B be the event that this person supports the death penalty. We want to find P(A and B).Which answer is correct, Answer 1 or 2?Answer 1: P(A and B) = P(A) * P(B) = 0.62(0.28) = 0.1736 We can use the Multiplication Rule for Independent Events because the events are independent. Having a college degree does not determine a person’s views on the death penalty.Answer 2: We do not have enough information to answer the question. We cannot use the Multiplication Rule for Independent Events because these events are dependent. Having a college degree affects the likelihood that a person supports the death penalty.

Polls on certain topics are conducted routinely in order to monitor changes in the public's opinions over time. One such topic is the death penalty. In 2003 a poll estimated that 64% of U.S. adults support the death penalty for a person convicted of murder. In a more recent poll, 675 out of 1,000 U.S. adults chosen at random were in favor of the death penalty for convicted murderers. Do the results of this poll provide evidence that the proportion of U.S. adults who support the death penalty for convicted murderers (p) changed between 2003 and the later poll?State the hypotheses

Forty-three percent of all registered voters in a particular state prefer life in prison without parole over the death penalty for a person convicted of first degree murder. Among Latino registered voters in the state, 66% prefer life in prison without parole over the death penalty for a person convicted of first degree murder. 37.5% of all citizens in the state are Latino.In this problem, define variables as the following.•   C = Registered voters preferring life in prison without parole over the death penalty for a person convicted of first degree murder.•   L = Latino citizensSuppose that one registered voter is randomly selected.Find P(L AND C ). (Round your answer to four decimal places.)P(L AND C ) =

A Gallup Poll in May 2004 estimated that roughly 70% of U.S. adults are in favor of the death penalty for a person convicted of murder. A random sample of 750 U.S. adults is chosen. Let X be the number of adults (out of 750) who favor the death penalty.The distribution of X is binomial. What are the values of n and p?

The following table represents the highest educational attainment of all adult residents in a certain town. If an adult is chosen randomly from the town, what is the probability that they have a high school degree or some college, but have no college degree?

A study was done of all homicide convictions in the State of Florida between 1976 and 1980 in order to examine if the application of the death sentence was racially biased. The data showed that a larger percentage of white suspects (11.2%) were sentenced to death than black suspects (8.5%). However, if the race of the victim was included in the analysis, the study found that for white victims, a larger percentage of black suspects (19.3%) were sentenced to death than white suspects (12.3%).Which of the following is correct? Check all that apply. “Race of the suspect” is a lurking variable in this situation. “Race of the victim” is a lurking variable in this situation. This is an example of Simpson’s paradox. This is an example of a negative association.
