Statistical decision and falsification in science: going beyond the null
... If we summarize, a scientifically useful hypothesis has to be probable, plausible and falsifiable. All point hypotheses (e.g. H0) are thus scientifically useless since they are improbable to the point of being false. Hypotheses that include every possible result except one (e.g. H1), are also scient ...

... = P(z>[20.5-18.4]/16.088) = P(z>0.52) = 0.5 – 0.1985) = 0.3015. Technically speaking, since p<0.1 in the case of W, we cannot use normal distribution as approximation for W. However, there is no direct way of combining two binomial distributions. Using the normal distribution, we can obtain the ans ...

According to the subjective de nition, the probability of an event is a measure of the degree of belief that the event will occur (or has occured). Degree of belief depends on the person who has the belief, so my probability for event A may ...
