What does it mean to find the expected value of a chance activity with numerical outcomes?
I think it means to find the theoretical probability of something random that has results that are numbers. For instance, rolling a die and trying to get a 6 is a "chance activity with numerical outcomes".
At a significance level of 0.01 which conclusion can the brewer draw?
That there is a 99% chance that the results of the brewer's study happened because of his manipulation of the IV and not by chance
Percent chance of rain?
A forecast that says, for instance, "there is a 10% chance of rain tomorrow," means that on 10 out of 100 days with weather conditions very similar to the conditions expected tomorrow, at least a trace of train has occurred. Some will disagree with this answer for various reasons. For the results of research that evaluated how understanding of percentage chance of precipitation varies around the world, see "A 30% Chance of Rain Tomorrow: How Does the Public Understand Probabilistic Weather Forecasts?," available as a PDF file via the URL http://www.mpib-berlin.mpg.de/en/mitarbeiter/gigerenzer/pdfs/RainFinal.pdf .
What is the importance of statistics in science and technology?
Statistics is used all the time in science and technology. In short, statistics tell us whether our results are probably caused by chance or not. Statistics is used in research to compare results between different treatments. It can also help describe relationships between variables and results over time. The most important thing is that it tells you when your differences are large enough to probably not be caused by chance. Statistics can also used in manufacturing by setting specification ranges and other quality attributes.
How can you explain the significance level of at statistics?
Significance Level (Alpha Level): If the level is set a .05, it means the statistician is acknowledging that there is a 5% chance the results of the findings will lead them to an incorrect conclusion.

Can a probation officer give you a second chance pay?
They can recommend. But, you have to have done the work asked of you and show up. This is a time for you to show tangible results of your efforts to follow through with what you have been expected to do.
What does The first law of probability state?
States that the results of one chance event have no effect on the results of subsequent chance events.
How much percent does it take so you know the experiment works?
Typically, if an experiment produces results that are statistically significant with a confidence level of at least 95%, it is considered to have worked. This means there is a 5% chance that the results are due to random chance rather than a true effect.
Do you have a chance to win a lottery this year?
If you have bought a ticket, then you have a chance. Your chance may not great, but as they say, if you are not in, you cannot win. No winner expected to win, but it could be you.
Is it mathematically better to take many small risks over a long period or just to take one big risk in order to accomplish the same outcome?
Mathematically you will end up with more (or having lost less) if you take multiple small risks. Pretend you are playing a casino and you have $100.In one game, you have a 15% chance to win 10x the amount. Your expected return is:[.15 (your chance of winning) x 1000] - [.85 (your chance of losing) x 100)That equals 65, so your expected return is $65. Overall you would lose $35In another game, you have an 80% chance to win 2x the amount. Again the same equation:[.85 x 200] - [.15 x 100]That equals $155. Overall you would win about $55Obviously this is statistics so it's possible you win much more taking the big risk than you do playing the small risk, just not probable.
When is the new moon movie expected to come out?
It's expected to come out in theaters in late 2009, although there is a chance it will come out early 2010.
What is meant by observed genotypes?
A phenotype is a physical characteristic. For a human an observed phenotype example would be hair colour (e.g brown) or eye colour (green). An observed phenotype is a physical characteristic that can be seen directly or indirectly (internal organs) caused by an individual's genotype.

they are fine; expected ratios might not been seen simply due to chance
Assumption that experimental results are due to chance alone is called?
null
What were citizens of the polis expected to do?
Citizens were expected to participate in government and defend the polis. Polis did not do so because they were denied the chance to do so.
How can you be sure of getting the expected ration from flipping a coin?
Flipping a coin has a 50:50 chance. The only way to get close to the expected ratio is to flip a lot of times. It is never guaranteed.
