The answer is 3) From calls made to one hundred randomly generated telephone numbers, people replied to a question about television shows they watch
This is because the people questioned were completely chosen at random and were asked about something they might or might know much about. This is easily the least biased option.
However, other surveys were not biased, e.g. asking heart surgeons about children's diet or asking ex-employees of The World of Baseball Bookstore about the importance of baseball.
These are not a random selection and might not actually provide accurate results.
Answer:
Some members could be alarmed but it doesn't necessarily mean that Community Hospital has lower-quality care than Middle Hospital and University Hospital. It is important to identify that this alarm could also come from the increased economic pressure on hospitals.
R.W. Dubois, R.H. Brook and W.H. Rogers (1987) have studied the death rate index as a potential screen for quality of medical care since the 80s. In their article, they state that hospital with higher death rates "may provide inadequate quality of care or have uniquely ills patient populations." This would lead the Quality Task Force to explore and define the ills patient population of the Community Hospital.
Mary E.Goss and Joseph I. Reed (1974) explore the quality evaluating practices of hospital care through severity-adjusted death rates in the 70s. Their analysis suggested that differences in technological adequacy, control status and teaching status of the hospitals partially support the validity of death rate as a quality index; but "the index is too dependent of the local population".
Therefore a population characterization must be necessary to bring up in this discussion as a cohort study. Goss and Reed also stated that the death rate "may be more productive in the long run". This means that the death rate would be better estimated in a longitudinal study as a quality care index.

In the united states, spending on social security, medicare, and Medicaid was approximately 3% of the Gross domestic product in 1962 and is expected to be approximately 20% of the Gross domestic product in 2050.
The gross domestic product is a measure of the market value of all the completed products and services produced in a country within a specific time period.
Due to the measurement's complexity and subjectivity, it must be constantly revised before it can be considered a reliable indication.
In contrast to nominal GDP, which is better for comparing national economies on the international market, utilizing a base of Gross domestic product per capita at purchasing power parity (PPP) may be more beneficial for comparing living standards between nations.
However, variations in the cost of living and inflation rates across the nations are not reflected in the nominal gross domestic product (GDP) per capita.
The contribution of each industry or sector to the overall Gross domestic

Answer:
executive
Explanation:
Executive functions of the brain enable us to stay and keep doing something while the internal and basic process in the foreground are happening.

In Africa, there are different climatic regions, different vegetation zones and different relief features.
Large percentages of people in Africa lived in the grasslands and semi-desert areas, where they were mainly pastoralists and nomads.
For those who lived around lakes and rivers, fishing was common, and they had a more settled lifestyle.
Keep in mind that African people had different communities, which all had different lifestyles, although this deals more with history than geography.
