What doeshypothesismean? Hypothesisis a noun that means “aproposition, or set of propositions, set forth as an explanation” that describe “some specified group of phenomena.” Sounds familiar totheory, no? But, unlike atheory, a scientifichypothesisis made before testing is done and isn’t ...
So what does intractable mean? If you are a professional complexity theorist, it means that it has no polynomial-time solution. But for an EDA engineer, polynomial time with a big index is the same as useless. In fact, any index bigger than 1. Even an O(n2) algorithm is intractable wh...
Economics does not naturally lend itself to scientifichypothesis testingas does physics. In the field of epistemology, scientists can learn through logical thought experiments, also called deduction, or through empirical observation and testing, also called positivism. Geometry is a logically deductive sci...
A hypothesis does not have to be right or wrong, but the person formulating it does have to be prepared to test the theory to its limits. If someone hypothesizes that exposure to X causes Y in lab rats, for example, he or she must see if exposure to other things also causes Y. Whe...

So if the null hypothesis is correct, then the probability the test is significant should be αα. If you then collect new data and test the new data, the probability the second test is significant should also be αα, and the conditional independence means the probability of both tests bei...
So who does know how to do that? Politicians? Economists? The problem with their solutions is the same problem that scientists face—they assume rational action from reasonable humans. But humans can be largely irrational. When it comes to the environment, we often function like well-meaning ad...
It does not tell us whether the Service Level of A is better or whether that of B is better. It merely tells us that they are different.It is important to understand whether the alternate hypothesis should be written in the directional or non-directional form. This is because the ...
wherein being a person of color has a negative effect on one's educational attainment. In reality,this hypothesis proves true, with the exception of Asian Americans, who go to college at a higher rate than whites do. However, Blacks and Hispanics and Latinos are far less likely than whites...
Hypothesis Testing:Hypothesis Testing is conducted assuming the null hypothesis is true and based on that, the test statistic value is calculated through which the p-value of the experiment can be found.Answer and Explanation: A p-value is compared with a significance level for making decisions ...
