Problem: Given the question: False precision (also called overprecision, fake precision, misplaced precision and spurious precision) occurs when numerical data are presented in a manner that implies better precision than is justified; since precision is a limit to accuracy, this often leads to overconfidence in the accuracy, named precision bias.[1] David has been working for the government for many years. His expertise is in statistics. He analyzes numerical data to help lawmakers make better decisions. He has now two sets of data in front of him, data set A and data set B. His evaluation finds that data set A is subject to false precision, but data set B is not subject to false precision. He has to decide which data set should be presented to the lawmakers. Would lawmakers make better decisions or worse decisions with data set B when accuracy matters?

The answer is:
better decisions

input question: Cholesterol has been implicated in heart disease for decades. Atherosclerosis is a disorder of the arteries in which cholesterol and other materials are deposited on the interior of the arterial wall. These deposits lead to the formation of plaques that can restrict or even block the flow of blood through these blood vessels (see Figure below ). A decrease in the flow of blood can lead to high blood pressure and a lowered oxygen supply to the heart muscle. A complete blockage of blood flow to parts of the heart (a heart attack) can cause significant damage due to oxygen deprivation, in some cases leading to death. Brad and Dale went to the doctor for a check up. Brad did some blood tests and found out he has very high cholesterol levels, while his partner Dale had normal cholesterol levels, and was very healthy. Brad got scared and started worrying. Which friend was at a lower risk of suffering a heart attack????
output answer: Dale

There is a large area of low ozone concentration or "ozone hole" over Antarctica. This hole covers almost the whole continent and was at its largest in September 2008, when the longest lasting hole on record remained until the end of December. The hole was detected by scientists in 1985 and has tended to increase over the years of observation. The ozone hole is attributed to the emission of chlorofluorocarbons or CFCs into the atmosphere, which decompose the ozone into other gases.Some scientific studies suggest that ozone depletion may have a dominant role in governing climatic change in Antarctica (and a wider area of the Southern Hemisphere). Ozone absorbs large amounts of ultraviolet radiation in the stratosphere. Ozone depletion over Antarctica can cause a cooling of around 6 C in the local stratosphere. This cooling has the effect of intensifying the westerly winds which flow around the continent (the polar vortex) and thus prevents outflow of the cold air near the South Pole. As a result, the continental mass of the East Antarctic ice sheet is held at lower temperatures, and the peripheral areas of Antarctica, especially the Antarctic Peninsula, are subject to higher temperatures, which promote accelerated melting. Models also suggest that the ozone depletion/enhanced polar vortex effect also accounts for the recent increase in sea ice just offshore of the continent. Blimpton and Jarmel are two neighboring planets in the Harshlan galaxy. Aliens are currently studying the two planets to see if either of them are suitable for habitation. While studying the planets, they discover that both planets have the same type of atmosphere. However, there is one key difference. The difference is that the current species of animals on Blimpton emit much more chlorofluorocarbons than Jarmel's animals do. The aliens take note of this so they can report back to their bosses on what they have found. Which planet's stratosphere is warmer?
----
Answer: Jarmel

Q: Beginning in September 2012, the U.S. Food and Drug Administration will require larger, more prominent cigarette health warnings on all cigarette packaging and advertisements in the United States. These warnings are a significant advancement in communicating the dangers of smoking. These new cigarette health warnings contains nine different warnings that will increase awareness of the specific health risks associated with smoking, such as death, addiction, lung disease, cancer, stroke and heart disease. These warnings include: Dahlia has smoked cigarettes every day for many years. Dahlia's daughter, Samantha, has never smoked a cigarette in her life. Besides this difference, Dahlia and Samantha have similar activity levels and eat a similar diet. Who has a higher risk of dying?
A: Dahlia

Question: The frequency of a wave is the same as the frequency of the vibrations that caused the wave. For example, to generate a higher-frequency wave in a rope, you must move the rope up and down more quickly. This takes more energy, so a higher-frequency wave has more energy than a lower-frequency wave with the same amplitude. You can see examples of different frequencies in the Figure below (Amplitude is the distance that particles of the medium move when the energy of a wave passes through them.) John was tuning his musical instruments with two tuning forks, fork A and fork B. He produced higher frequency with fork A and lower frequency with fork B. Interestingly, both frequencies had the same amplitude. Which fork's wave would have more energy, fork A or fork B?
Answer: fork A

Please answer this: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth's surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465C (860F). That's hot enough to melt lead! Brad and Joe studied atmospheric conditions on different planets of our solar system. Joe studied about Earth, while Brad studied more about Venus. Which person didn't find out that Venus is much hotter than Mercury?

Brad
