I have several questions.

say what kind of individuals the population consists of and say exactly which individuals fall in the population. If the information given is not sufficient, complete the description of the population by making reasonable assumptions about any missing information.

(a) An opinion poll contacts 972 American adults and asks them, "Would you rather have a job working for the government or working for business?"

(b) Video adapter cables have pins that plug into slots in a computer monitor. The adapter will not work if pins are bent or broken. A computer store buys video adapter cables in large lots form a supplier. The store chooses five cables from each lot and inspects the pins. In any of the cables have bent or broken pins, the entire lot is sent back.

(c) The American Community Survey contacts 3.5 million households, including some in every country in the United States. This Census Bureau survey asks each household questions about heir housing, economic, and social status.

Comment on each of the following as a potential sample survey question. Is the question clear? Is it slanted toward a desired response? (Survey questions on issues that one might regard as inflammatory are often prone to slanted wording).

(a) "Which of the following best represents your opinion on gun control?

1. The government should take away our guns.

2. We have the right to keep and bear arms."

(b) "In light of skyrocketing gasoline prices, we should consider opening up a very small amount of Alaskan wilderness for oil exploration as a way of reducing our dependence on foreign oil. Do you agree or disagree?"

(c) "Do you think that the excessive restrictions placed on U.S. law enforcement agencies hampered their ability to detect the 9/11 terrorist plot before it occurred?"

(d) "Do you use drugs?"

An article in a medical journal reports on an experiment to see the effect of eating three whole eggs per day on cholesterol levels as compared to eating the equivalent amount of a yolk-free egg substitute. The article describes the experiment as a randomized, single-blinded experiment of 37 subjects with metabolic syndrome. What do you think "single-blinded" mean here? Why isn't a double-blind experiment possible?

The number of Americans living below the official poverty line increased from 35,574,000 to 39,698,000 in 20 years between 1997 and 2017. What percentage increase was this? You should not conclude form these values alone that poverty became more common during this time period. Why not?
